Value of \( \Large \left( \frac{2^{-3}}{5} \right) ^{-2}\) is

A) \( \Large \frac{1}{1600} \)
B) 1600
C) \( \Large \frac{1}{40} \)
D) 40

Correct Answer:


B) 1600

Description for Correct answer:

\( \Large \left( \frac{2^{-3}}{5} \right)^{-2} \)

= \( \Large \left( \frac{1}{5}\times \frac{1}{2^3} \right)^{-2} \)

= \( \Large \left(\frac{1}{40} \right)^{-2} \)

= \( \Large 40^{2} \)

= 1600
