Please help!

Give the square and the cube of each expression in simplified form.

-2t^2k

(-2t^2k)^2 = (-2)^2 (t^2)^2 (k)^2 = 4t^4k^2

Now you can see how to do the cube, right?

Now I get it, thanks Steve.

To find the square and the cube of the expression -2t^2k, we will simplify each expression separately.

Let's start with the square of -2t^2k:
Squaring a term means multiplying it by itself. So, we'll multiply -2t^2k by itself:
(-2t^2k) * (-2t^2k) = 4t^4k^2

Therefore, the square of -2t^2k is 4t^4k^2.

Now, let's find the cube of -2t^2k:
Cubing a term means multiplying it by itself two more times.
(-2t^2k) * (-2t^2k) * (-2t^2k) = -8t^6k^3

Thus, the cube of -2t^2k is -8t^6k^3.

In simplified form, we have:
Square of -2t^2k: 4t^4k^2
Cube of -2t^2k: -8t^6k^3
