Question

The cube of a number decreased by 4?

Answer 1

Hi there!

We're asked to find the cube of a number decreased by 4.

So first, we'll choose a letter to represent our variable. I'll choose m.

Next, we should find the cube of m:

`\text{the cube of m = }{\rm{m^3}`

The next step is to subtract 4 from the cube of m:

`\sf{m^3-4}`

Therefore, the expression is
`m^3-4}`.
