Hello from MrBillDoesMath!
Answer:
1/64
Discussion:
(2^3) ^ (-2) => 2^3 = 2 * 2 *2 = 8
= 8^(-2) => negative exp gives reciprocal of time to same
power
= ( /8)^2 => 8*8 = 64
= 1/64
NOTE; the answer shown selected in the diagram is incorrect as the correct result is a positive, NOT negative, number. The second choice is the correct one.
Thank you,
MrB
