(3x-1)^3^ = exponents, so it's (3x-1) cubed

You did not specify what is the required
information.

I assume that you either need to expand or
find the roots.

First, let us expand between brackets using
the formula:

We know
that:

`(a-b)^3 = a^3 - 3a^2 b +3ab^2 -
b^3`

`==> (3x-1)^3 = 27x^3 -27x^2 +9x
-1`

`` If you need to determine the roots (
zeros):

==> `(3x-1)^3 =
0`

`==> 3x-1 =
0`

`==> 3x =
1`

`==> x =
1/3`
