Question

What is (-3x) 4 in expanded form?

Answer 1

It is 3x^2 -12x hope it helps.

Answer 2

`81 x^4`.

Explanation:

We have given expression
`(-3x)^4`.

We need to find the expanded form of given expression.

We can see that -3x has a whole power(exponent) as 4.

So, we need to distribute 4 over exponents of -3 and x.

Therefore,

`(-3x)^4 =(-3)^4*(x)^4`

=
`81 x^4`.

Therefore, expanded form of
`(-3x)^4` is
`81 x^4`.
