Quizplus · Accepted Answer

When multiplying these expressions, you multiply the coefficients (-5 and -2) to get 10, and then apply the rule for multiplying variables with exponents (add the exponents for the same base), resulting in $x^{1+1}y^{1+2} = 10x^2y^3$.

Multiply - (−5xy)(−2xy2)( - 5 x y ) \left( - 2 x y ^ { 2 } \right)(−5xy)(−2xy2)

Multiply
- $( - 5 x y ) \left( - 2 x y ^ { 2 } \right)$
