Fatima evaluated the expression 4m n-2 need help plzzz
Alekssandra [29.7K]

Answer:

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

Step-by-step explanation:

we have the expression

\frac{4m^{-3}n^{-2}}{m^{-1} n}

Simplify

\frac{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

Form=-2, n=4

4(-2)^{(-2)}(4)^{(-3)}=4(\frac{1}{4})* (\frac{1}{64})=\frac{1}{64}

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