Question

Divide. (−10m9 − 4m8 − 12m6) ÷ 2m4

Answer 1

Answer:

A. $- 5m^{5}-2m^{4}-6m^{2}$

Step-by-step explanation:

When dividing a few units by the same number. they can be split and individually divided before subtracting them from each other. When dividing with numbers with exponents, the exponents are subtracted from one another, while the base numbers are divided:

$\frac{-10m^{9} -4m^{8}-12m^{6}}{2m^{4}} \\\\=\frac{-10m^{9} }{2m^{4}} -\frac{4m^{8} }{2m^{4}}-\frac{12m^{6} }{2m^{4}}\\\\= - 5m^{5}-2m^{4}-6m^{2}$

Answer 2

The answer is A -5m^5-2m^4-6m^2
