Respuesta :

It is 3x^2 -12x hope it helps.

Answer:

[tex]81 x^4[/tex].

Step-by-step explanation:

We have given expression [tex](-3x)^4[/tex].

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,

[tex](-3x)^4 =(-3)^4\times(x)^4[/tex]

           = [tex]81 x^4[/tex].

Therefore, expanded form of  [tex](-3x)^4[/tex] is  [tex]81 x^4[/tex].
