Question
Which of the following is equivalent to (10^2)^n+1 ?
- 10^2(10^2 n)
- 10^2(10^n+1)
- 10^2 n+3
- 10(10^2 n)
- (10^2 n)^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 10^2n
