multiply.\n-4x^{2}cdot7x\nsimplify your answer as much as possible.

Explanation:

Step1: Multiply coefficients

Multiply -4 and 7. $-4\times7=-28$

Step2: Multiply variables

Use the rule of exponents $a^m\times a^n=a^{m + n}$ for $x^2\times x$. Here $m = 2$ and $n=1$, so $x^2\times x=x^{2 + 1}=x^3$.

Step3: Combine results

Combine the results of step 1 and step 2. $-28x^3$

Answer:

$-28x^3$
