Question
Which of the following is equivalent to \left(10^{2}\right)^{n+1} ?
- 10^{2}\left(10^{2 n}\right)
- 10^{2}\left(10^{n+1}\right)
- 10^{2 n+3}
- 10\left(10^{2 n}\right)
- \left(10^{2 n}\right)^{2}
Topics: exponents
Solution
Step 1
We apply the exponent-of-a-power rule to simplify the nested exponent.
(10^2)^{n+1} = 10^{2(n+1)}
Step 2
We distribute the exponent multiplication inside the parentheses.
2(n+1) = 2n + 2
Step 3
We use the property of multiplying exponents with the same base to split the result into a product.
10^{2n+2} = 10^2 \times 10^{2n}
Answer
A
