Insert the corresponding expression:
To solve this problem, we'll follow these steps:
Step 1: Identify the common base in both the numerator and the denominator.
Step 2: Apply the Power of a Quotient Rule for Exponents.
Step 3: Simplify the expression by subtracting the exponents.
Now, let's work through each step:
Step 1: Notice that both the numerator and the denominator share the same base, .
Step 2: The Power of a Quotient Rule states that . We apply this rule to our expression, obtaining .
Step 3: Simplifying , we find that the expression simplifies to .
Therefore, the simplified form of the expression is .
Considering the given answer choices:
Choice 1: is incorrect because it involves adding the exponents, which does not follow the rules for division of powers.
Choice 2: is the correct as the setup simplification, and can be fully simplified to yield for clarity.
Choice 3: is incorrect because it multiplies the exponents, which is not applicable in division.
Choice 4: is not directly applicable as it assumes a different interpretation not aligning with subtraction of exponents for division.
The correct choice is represented by choice 2, .
Insert the corresponding expression:
\( \frac{9^{11}}{9^4}= \)
Think of it this way: . You can cancel out two x's from top and bottom, leaving four x's on top, which is !
You still subtract! For example, . The negative exponent means one divided by that positive power: .
No! This rule only works when the bases are identical. For , you cannot subtract exponents because x and y are different bases.
Use this memory trick: Multiplication = Add exponents (), Division = Subtract exponents (). Think 'multiply-add' and 'divide-subtract'!
If your answer is , you should complete the subtraction to get . Always simplify arithmetic in exponents for the clearest final answer.
