Question

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

Answer 1

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

Answer 2

The simplified form of given expression is
`84(x^(12))`.

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))`.
