Describe how to simplify the expression

3^-6 / 3^-4 = 3^[-6 -(-4)] = 3^-6 + 4 = 3^-2

so answer is D last option

Keep the base the same and then subtract the exponents

Amount of simple interest in three year = 750

Step-by-step explanation:

Given:

Amount invested = 5,000

Number of year = 3 year

Rate of interest = 5% Annually

Find:

Amount of simple interest in three year

Computation:

Simple interest = (P){R)(T)

Amount of simple interest in three year = (5,000)(3)(5%)

Amount of simple interest in three year = (5,000)(3)(0.05)

Amount of simple interest in three year = (5,000)(0.15)

Amount of simple interest in three year = 750
