Understanding Power of a Product

Complete explanation with examples

When finding an expression with multiplication or an exercise that has only multiplication operations inside a parenthesis and the wholes expression is raised to a certain exponent, we can take the exponent and apply it to each of the terms of the expression or exercise.
We must not forget to keep the multiplication signs between the terms.
Property formula:
(a×b)n=an×bn (a\times b)^n=a^n\times b^n

Exercise #1

Choose the expression that corresponds to the following:

(10×3)4= \left(10\times3\right)^4=

Step-by-Step Solution

To solve this problem, we'll apply the power of a product rule to the expression (10×3)4(10 \times 3)^4.

  • Step 1: Identify the expression.
    The given expression is (10×3)4(10 \times 3)^4.

  • Step 2: Apply the power of a product law.
    According to the rule, (a×b)n=an×bn(a \times b)^n = a^n \times b^n, our expression becomes:
    (10×3)4=104×34(10 \times 3)^4 = 10^4 \times 3^4.

  • Step 3: Evaluate the choices:
    - First choice: 34×1043^4 \times 10^4
    Rearranging terms, this is equivalent to 104×3410^4 \times 3^4. Therefore, it matches our transformed expression.
    - Second choice: 30430^4
    Since 30=10×330 = 10 \times 3, (10×3)4=304(10 \times 3)^4 = 30^4. This simplifies to the same expression.
    - Third choice: 104×3410^4 \times 3^4

    Therefore, the solution is that all answers are correct.

Exercise #2

Choose the expression that corresponds to the following:

(12×3)5= \left(12\times3\right)^5=

Step-by-Step Solution

The given expression is (12×3)5 (12 \times 3)^5 . The power of a product rule states that (a×b)n=an×bn(a \times b)^n = a^n \times b^n. We will apply this formula to the expression.

  • Firstly, identify the base of the power as the product 12×312 \times 3.

  • Secondly, recognize that the exponent applied to this product is 5.

  • According to the rule, the power of a product can be distributed to each factor in the product, which means: (12×3)5=125×35(12 \times 3)^5 = 12^5 \times 3^5.

Therefore, the expression (12×3)5 (12 \times 3)^5 corresponds to 125×35 12^5 \times 3^5 .

Answer:

125×35 12^5\times3^5

Exercise #3

Choose the expression that corresponds to the following:


(13×4)6= \left(13\times4\right)^6=

Step-by-Step Solution

The expression in question is (13×4)6 \left(13\times4\right)^6 . This expression involves raising a product to a power and requires the application of the power of a product exponent rule, which states:

  • When you have a product raised to an exponent, you can distribute the exponent to each factor in the product separately.

Mathematically, any numbers a a and b b and a positive integer n n can be written as(a×b)n=an×bn (a \times b)^n = a^n \times b^n .

Applying this rule to our expression, (13×4)6 \left(13 \times 4\right)^6 becomes 136×46 13^6 \times 4^6 .

Therefore, the expression (13×4)6 \left(13 \times 4\right)^6 simplifies to 136×46 13^6 \times 4^6 .

Answer:

136×46 13^6\times4^6

Exercise #4

Choose the expression that corresponds to the following:

(2×11)5= \left(2\times11\right)^5=

Step-by-Step Solution

To solve the expression, we can apply the rule for the power of a product, which states that(a×b)n=an×bn \left(a \times b\right)^n = a^n \times b^n .

In this case, our expression is (2×11)5 \left(2\times11\right)^5 , wherea=2 a = 2 and b=11 b = 11 , and n=5 n = 5 .

Applying the power of a product rule gives us:

  • an=25 a^n = 2^5

  • bn=115 b^n = 11^5

Therefore, (2×11)5=25×115 \left(2\times11\right)^5 = 2^5 \times 11^5 .

Answer:

25×115 2^5\times11^5

Exercise #5

Choose the expression that corresponds to the following:

(2×4)10= \left(2\times4\right)^{10}=

Step-by-Step Solution

To solve the question, we need to apply the power of a product exponent rule. The formula states that for any real numbers a a and b b , and any integern n :

  • (a×b)n=an×bn (a \times b)^n = a^n \times b^n

Looking at our expression, we can see that:

  • a=2 a = 2

  • b=4 b = 4

  • n=10 n = 10

Now, if we apply the formula:

  • (2×4)10=210×410 (2 \times 4)^{10} = 2^{10} \times 4^{10}

Therefore, the expression (2×4)10 (2 \times 4)^{10} is equivalent to 210×410 2^{10} \times 4^{10} .

Answer:

210×410 2^{10}\times4^{10}

Frequently Asked Questions

What is the power of a product rule in math?

+
The power of a product rule states that (a×b)^n = a^n×b^n. When you have multiplication inside parentheses raised to an exponent, you can distribute that exponent to each factor while keeping the multiplication sign between terms.

How do you solve (2×3)^4 using power of product rule?

+
Apply the exponent to each factor: (2×3)^4 = 2^4×3^4 = 16×81 = 1,296. This is often easier than calculating (2×3)^4 = 6^4 = 1,296 directly.

Can you use power of product rule with variables and coefficients?

+
Yes! For example, (3x)^2 = 3^2×x^2 = 9x^2. The rule applies to any multiplication expression, whether it contains numbers, variables, or both.

What's the difference between power of product and power of power rules?

+
Power of product: (ab)^n = a^n×b^n (distribute exponent to factors). Power of power: (a^m)^n = a^(mn) (multiply exponents). You often use both rules together in complex expressions.

How do you simplify (2^2×x^3)^2 step by step?

+
First apply power of product: (2^2)^2×(x^3)^2. Then use power of power rule: 2^(2×2)×x^(3×2) = 2^4×x^6 = 16x^6.

When should you simplify inside parentheses first?

+
Simplify first when you have like bases that can be combined. For example, in (2×x×x^2×3)^2, first combine: (6x^3)^2, then apply the power rule: 36x^6.

What are common mistakes with power of product problems?

+
Common errors include: forgetting to apply the exponent to all factors, losing multiplication signs, confusing power of product with power of power rules, and not simplifying coefficients properly.

Does power of product work with more than two factors?

+
Yes! The rule extends to any number of factors: (a×b×c×d)^n = a^n×b^n×c^n×d^n. Apply the outside exponent to each factor individually while maintaining all multiplication operations.
