Indices expressions

Indices are expressions that consists of base and exponents

Given the expression below;

(2²×2⁻⁵)/5²

Simplify the numerator to have:

2²×2⁻⁵ = 4 * 1/2^5
2²×2⁻⁵ = 4 * 1/32

2²×2⁻⁵ = 1/8

2²×2⁻⁵ = 2^-3

Therefore;

(2²×2⁻⁵)/5^-2 = 1/8 * 25

(2²×2⁻⁵)/5² = 25/8

Hence the simplified form of the indices expression is twenty-five eighths
