r⁻⁸ * s ⁻⁵ = s ⁵ * r⁸
Step-by-step explanation:
r⁻⁸ * s ⁻⁵ * r⁻⁸ * s ⁻⁵ = 1
=> r⁻⁸ * s ⁻⁵ = 1/r⁻⁸ * s ⁻⁵
=> r⁻⁸ * s ⁻⁵ = r⁸ * s ⁵
=> r⁻⁸ * s ⁻⁵ = s ⁵ * r⁸
while owen shown that
r⁸ * s ⁵ = s ⁵ * r⁸
so Owen has wronglu changes the sign of powers

Answer:
Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.
