Answer 1

Answer:

Given : ${\sf{\ \ \left( {\dfrac{1}{2^3}} \right)^2}}$

• Identity : (a/b)ᵐ = (aᵐ)/(aᵐ)

Here, a = 1, b = 2, m= 2

$\implies{\sf{ {\dfrac{(1)^2}{(2^3)^2}}}}$

• Identity : (aᵐ)ⁿ = (a)ᵐⁿ

Here, a = 2, m = 3, n = 2

$\implies{\sf{ {\dfrac{1}{(2)^{3 \times 2}}}}}$

$\implies{\sf{ {\dfrac{1}{(2)^6}}}}$

$\implies{\sf{ {\dfrac{1}{64}}}}$

Hence, the final answer is 1/64.
