What do you do when you are trying to square something?

When we are trying to square a number say x, to x², then we multiply the number x with number of powers

here since it is x² we multiply x * x

if it is x³, then x * x * x

The square of "something" is ... "something" multiplied by itself.

Here are some examples:

the square of 3 is ... 3² the square of x is ... x² the square of the sum of x and 1 is ... (x + 1) ²
