Question

Please help me with this.​

Answer 1

Answer: option 3 is correct

Step-by-step explanation: Simplify the expression.−8m^5z^6

Answer 2

Answer is #3) -8 m^5 z^6

When we multiply numbers with variable with exponents, we multiply the coefficients and add the exponents.

( -4m^3 z^4 ) ( 2m^2 z^2 )

-4 * 2 = -8
m^3 + m^2 = m^5
z^4 + z^2 = z^6

So

-8 m^5 z^6 is your answer
