Question

Owen simplified the expression r-8 s-5. r−8s−5 = 1 r8 ⋅ s5 = s5 r8 Describe Owen’s error.

Answer 1

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 2

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.
