Let's find 'X' if the square root of 'X' is 7

First, we have a square root sign. The square root of 'X' means what number, when squared, would give us 'X'

We know that the square root of 'X' is 7, so we know that 7, squared, would give us 'X'

7 squared is 7 times 7, which is 49

So if the square root of 'X' is 7, then 'X' must be 49
