Answer: C
Explanation:
from the expression, (⁵/₈)⁻²
Recall from the laws of indicies,
a⁻¹ = ¹/a , it is called reciprocal law in indicies.
Therefore,
(⁵/₈)⁻² = ¹/(⁵/₈)²
= ¹(²⁵/₆₄)
Therefore, to resolve this, it will be
1 ÷ ²⁵/₆₄
= 1 ˣ ⁶⁴/₂₅
= ⁶⁴/₂₅
The answer is ⁶⁴/₂₅ which is C in the provided options.
