Question

Find the product of $11x{y}^{2}and-8x{y}^3$.

• A. $-88x^2{y}^5$
• B. $-80x^2{y}^5$
• C. $-88x^3{y}^5$
• D. $-80x^2{y}^4$

Answer 1

The correct option is A

$-88x^2{y}^5$

$\left(11x{y}^2\right)\times (-8x{y}^3)$
= $-(11\times 8)\times x\times x\times y^2\times y^3$
= $-(11\times 8)x^{(1+1)}{y}^{(2+3)}$
= $-88x^2{y}^5$
