Understanding Exponents Rules

Complete explanation with examples

Definition of Exponentiation

Exponents are a way to write the multiplication of a term by itself several times in a shortened form.

The number that is multiplied by itself is called the base, while the number of times the base is multiplied is called the exponent.

A - Exponentiation

an=aaa a^n=a\cdot a\cdot a ... (n times)

For example:

5555=54 5\cdot5\cdot5\cdot5=5^4

5 5 is the base, while 4 4 is the exponent.

In this case, the number 5 5 is multiplied by itself 4 4 times and, therefore, it is expressed as 5 5 to the fourth power or 5 5 to the power of 4 4 .

Exercise #1

(23)6= (2^3)^6 =

Step-by-Step Solution

To solve the given expression (23)6 (2^3)^6 , we apply the power of a power rule (am)n=amn (a^m)^n = a^{m \cdot n} . Here, a=2 a = 2 , m=3 m = 3 , and n=6 n = 6 .

Thus, we calculate the exponent:

36=18 3 \cdot 6 = 18

So, (23)6=218 (2^3)^6 = 2^{18} .

Answer:

218 2^{18}

Exercise #2

(43)2= (4^3)^2=

Step-by-Step Solution

To solve (43)2 (4^3)^2 , we use the power of a power rule which states that (am)n=amn (a^m)^n = a^{m \cdot n} .

Here, a=4 a = 4 , m=3 m = 3 , and n=2 n = 2 .

So, we calculate 432 4^{3 \cdot 2} ,

which simplifies to 46 4^6 .

Answer:

46 4^6

Exercise #3

Solve the following problem:

13= 1^3=

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the given information

  • Step 2: Apply the appropriate exponent rule

  • Step 3: Perform the calculation

Now, let's work through each step:
Step 1: The problem gives us the expression 13 1^3 . This means we have a base of 1 and an exponent of 3.
Step 2: We'll use the exponentiation rule, which states that an=a×a××a a^n = a \times a \times \ldots \times a (n times).
Step 3: Since our base is 1, raising 1 to any power will still result in 1. Therefore, we can express this as 1×1×1=1 1 \times 1 \times 1 = 1 .

Therefore, the solution to 13 1^3 is 1 1 .

Exercise #4

Solve the following problem:

70= 7^0=

Step-by-Step Solution

To solve the problem of finding 70 7^0 , we will follow these steps:

  • Step 1: Identify the general rule for exponents with zero.

  • Step 2: Apply the rule to the given problem.

  • Step 3: Consider the provided answer choices and select the correct one.

Now, let's work through each step:

Step 1: A fundamental rule in exponents is that any non-zero number raised to the power of zero is equal to one. This can be expressed as: a0=1 a^0 = 1 where a a is not zero.

Step 2: Apply this rule to the problem: Since we have 70 7^0 , and 7 7 is certainly a non-zero number, the expression evaluates to 1. Therefore, 70=1 7^0 = 1 .

Therefore, the solution to the problem is 70=1 7^0 = 1 , which corresponds to choice 2.

Exercise #5

Solve the following problem:

(3)0= \left(-3\right)^0=

Step-by-Step Solution

To solve this problem, let's follow these steps:

  • Understand the zero exponent rule.

  • Apply this rule to the given expression.

  • Identify the correct answer from the given options.

According to the rule of exponents, any non-zero number raised to the power of zero is equal to 11. This is one of the fundamental properties of exponents.
Now, apply this rule:

Step 1: We are given the expression (3)0(-3)^0.
Step 2: Here, 3-3 is our base. We apply the zero exponent rule, which tells us that (3)0=1(-3)^0 = 1.

Therefore, the value of (3)0(-3)^0 is 11.

Frequently Asked Questions

How do you multiply exponents with the same base?

+
When multiplying powers with the same base, add the exponents: a^n × a^m = a^(n+m). For example, 5^2 × 5^3 = 5^(2+3) = 5^5. The base stays the same, only the exponents are added together.

What is the rule for dividing exponents with the same base?

+
When dividing powers with the same base, subtract the exponents: a^n ÷ a^m = a^(n-m). For example, 7^5 ÷ 7^2 = 7^(5-2) = 7^3. Remember the base cannot be zero when using this rule.

How do you solve power of a power problems?

+
For power of a power, multiply the exponents: (a^n)^m = a^(n×m). For example, (3^2)^4 = 3^(2×4) = 3^8. This rule applies when you have parentheses around a base with an exponent, and another exponent outside.

What happens when you raise a number to the power of zero?

+
Any non-zero number raised to the power of zero equals 1: a^0 = 1. For example, 5^0 = 1, (-3)^0 = 1, and 100^0 = 1. However, 0^0 is undefined in mathematics.

How do you work with negative exponents?

+
A negative exponent means taking the reciprocal: a^(-n) = 1/a^n. Steps to solve: 1) Move the base to the denominator, 2) Make the exponent positive, 3) Simplify. For example, 2^(-3) = 1/2^3 = 1/8.

What are the most common mistakes students make with exponent rules?

+
Common errors include: 1) Adding exponents when multiplying different bases (2^3 × 3^2 ≠ 5^5), 2) Multiplying exponents instead of adding when multiplying same bases, 3) Forgetting that only the exponents change, not the base, 4) Confusing negative exponents with negative numbers.

Can you use exponent rules with variables and algebraic expressions?

+
Yes, exponent rules work the same way with variables. Examples: x^3 × x^5 = x^8, (y^2)^4 = y^8, and (2x)^3 = 2^3 × x^3 = 8x^3. The key is treating variables like any other base and applying the same rules consistently.

How do you handle exponents with fractions and multiplication?

+
For fractional bases: (a/b)^n = a^n/b^n. For products: (a×b)^n = a^n × b^n. Example: (2×3)^2 = 2^2 × 3^2 = 4 × 9 = 36. These distributive properties make complex expressions easier to solve step by step.
