Answer:

The number is 7.

Explanation:

To do this we need to go backwards,

First let's simplify this,
5^(2) = 25.

25 - 4 = 21 (We got this because since we are going backwards we do a reverse equation, the opposite of + is - so we subtract.

21 divided by 3 = 7, The opposite of multiplication is division.

So this means that our unknown number value is 7.

Hope that helps. x
