What is the product of -8(7-3.2)

Anton [14]

It should be 30.4

Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2)
You should end up with -56 + 25.6
Next you add those two numbers and you end up with 30.4.

I hope this helps!

Which expression is equivalent to (m8n-4) 1/4

ser-zykov [4K]

Answer:

D. $\dfrac{m^2}{n}$

Step-by-step explanation:

I assume this is your problem:

$(m^8n^{-4})^{\frac{1}{4}}$

If so, then this is the solution.

$(m^8n^{-4})^{\frac{1}{4}} =$

$= m^{8 \times \frac{1}{4}} n^{-4 \times \frac{1}{4}}$

$= m^2 n^{-1}$

$= \dfrac{m^2}{n}$
