Answer:
1/64
Step-by-step explanation:
Rewrite the expression using the negative exponent rule b⁻n = 1/bⁿ.
1/16³/²
simplify the denominator
rewrite 16 as 4²
1/(4²)³/²
Apply the power rule and multiply exponents, (aⁿ)ᵃ=aⁿᵃ
1/4²(³/²)
Cancel the common factor of 2
Cancel the common factor
then rewrite the expression
1/4³
Raise 4 to the power of 3
1/64
