Question

What is the product (4x)(-3x^8)(-7x^3)

Answer 1

Answer:

The simplified form of given expression is $84(x^{12})$.

Step-by-step explanation:

The given expression is

$(4x)(-3x^8)(-7x^3)$

We need to find the product of given expression.

First multiply the coefficients.

$(4)(-3)(-7)(x)(x^8)(x^3)$

$84(x)(x^8)(x^3)$

Using power property of exponent, we get

$84(x^{1+8+3})$               $[\because x^mx^n=x^{m+n}]$

$84(x^{12})$

Therefore the simplified form of given expression is $84(x^{12})$.

Answer 2

Multiply the constants, add up the exponents
4*(-3)*(-7)=84
1+8+3=12
so the result is 84x^12
