Question

Fatima evaluated the expression 4m n-2 need help plzzz

Answer 1

Answer: It’s C

Explanation:

Juss took a test

Answer 2

She applied the exponent -2 to 4(-2) instead of applying the exponent to just -2

Explanation:

we have the expression

`(4m^(-3)n^(-2))/(m^(-1) n)`

Simplify

`(4m^(-3)n^(-2))/(m^(-1) n)=4m^((-3+1))n^((-2-1))= 4m^((-2))n^((-3))`

Substitute the values of m and n in the expression

For
`m=-2, n=4`

`4(-2)^((-2))(4)^((-3))=4((1)/(4))* ((1)/(64))=(1)/(64)`

She applied the exponent -2 to 4(-2) instead of applying the exponent to just -2
