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
