A) $- 11 x ^ { 11 } y ^ { 3 }$
B) $28 x ^ { 30 } y ^ { 3 }$

D) $28 x ^ { 11 } y ^ { 4 }$

Question

Quizplus · Accepted Answer

When multiplying two algebraic expressions, you multiply the coefficients together and add the exponents of like bases. Here, $(-7) \times (-4) = 28$, $x^{5} \times x^{6} = x^{11}$, and $y \times y^{3} = y^{4}$, resulting in $28x^{11}y^{4}$.

Multiply - (−7x5y)(−4x6y3)\left( - 7 x ^ { 5 } y \right) \left( - 4 x ^ { 6 } y ^ { 3 } \right)(−7x5y)(−4x6y3)

Multiply
- $\left( - 7 x ^ { 5 } y \right) \left( - 4 x ^ { 6 } y ^ { 3 } \right)$
