Multiply.<br> 12x^4 (-5/6x^3y^2)

Darya [45]

Answer:

-10 $x^{7}$ $y^{2}$

Step-by-step explanation:

12 $x^{4}$ ( $-\frac{5}{6} x^{3}$ $y^{2}$ )
First multiply 12 * - $\frac{5}{6}$ , solving this you get -10
Next multiply $x^{4}$ by $x^{3}$ , solving this you get $x^{7}$

Finally you have $y^{2}$ , and nothing to multiply it by. So it stays as $y^{2}$

Put is all together and you get -10 $x^{7}$ $y^{2}$
