Answer 2

Answer:
`84x^(12)`

Explanation:

The given expression :
`(4x)(-3x^8) (-7x^3)`

Open brackets, we get

`4x\cdot-3x^8\cdot-7x^3\\\\=4\cdot-3\cdot-7\cdot x\cdot x^8\cdot x^3`

Using law of exponents:-

`a^m\cdot a^n=a^{m+n]`

`84\cdot x^(1+8+3)\\\\=84x^(12)`

Hence, the product
`(4x)(-3x^8) (-7x^3)=84x^(12)`
