Question

4x^3 y(-2x^2 y) -8x 6 y-8x 5 y-8x 5 y 22x 5 y 2

Answer 1

Answer:

$\boxed{\bold{-8x^5y^2}}$

Step By Step Explanation:

Remove Parenthesis: (a) = a

$\bold{-4x^3y\cdot \:2x^2y}$

Multiply: $\bold{4 \ \cdot \ 2 \ = \ 8}$

$\bold{-8x^3x^2yy}$

Apply Exponent Rule $\bold{\:a^b\cdot \:a^c=a^{b+c}: \ x^3x^2=\:x^{3+2}=\:x^5}$

$\bold{-8x^5yy}$

Apply Exponent Rule: $\bold{yy=\:y^{1+1}=\:y^2}$

$\bold{-8x^5y^2}$
