What are the two ways to write a number squared?

Answer 1

1: 2X2

2: the number then the smaller number above the big number

Squaring a number means to multiply it by itself. Using the number 3 as an example, you can write out the multiplication expression:

3X3

or use an exponent, which is a superscripted number indicating how many times to multiply the base by itself. In this case, it's twice:

32
