Quizplus · Accepted Answer

When multiplying variables with exponents, you add the exponents of the same variable and multiply the coefficients. Therefore, in this problem, you get $-20x^5z^6$.

Multiply - −5x2z4⋅4x3z2- 5 x ^ { 2 } z ^ { 4 } \cdot 4 x ^ { 3 } z ^ { 2 }−5x2z4⋅4x3z2

Multiply
- $- 5 x ^ { 2 } z ^ { 4 } \cdot 4 x ^ { 3 } z ^ { 2 }$
