Question

he sides of a square are five to the power of two fifths inches long. What is the area of the square?

Answer 1

It would be 1.9 in.*1.9 in.
1.9*1.9≈3.6 inches^2

Answer 2

So, the area of a square is Length times width, but since it is a square, the value for the length is the wame as the widtch. So, since one side is 5^2/5, would you multiply 5^2/5 by itself. When you multiple something with the same bade, you would add the power. So, the answer would be 

5^4/5
