Which expression is equivalent to (7^3)^−2?

Step-by-step explanation:

We are missing the rest of the question.

However (7^3)^-2 would equal to 343^-2 which would equal to 1/117649 or 8.49985 * 10^-6.

If you break it down more:

7*7*7= 343 Take that to the -2 power is 1/117649 or 8.49985*10^-6

If none of these is part of your choice, please supply the choices and I can try to help some more.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
