So, this question is asking you to use SUBSTITUTION. You will substitute the value 5 for X and 2 for Y in the following expression:
X2Y
So, you will simply replace or substitute 5 for X and do the same with 2 for Y.
Now our expression looks like this:
52•2
Simplified to 54
54
5 • 5 • 5 • 5
25 • 5 • 5
125 • 5 = 625
