If you use a guess and check method, you see that 42 = 16 and 62 = 36 Since 16 < 25 < 36 the next logical step would be checking 52
52 = 5 x 5 52 = 25 <--- We match our original number!!! Therefore, √25 = 5
Another method is to list out the products of integers starting at 1 as follows:
12 = 1 x 1 = 1 <--- Not our answer since 1 < 25 22 = 2 x 2 = 4 <--- Not our answer since 4 < 25 32 = 3 x 3 = 9 <--- Not our answer since 9 < 25 42 = 4 x 4 = 16 <--- Not our answer since 16 < 25 52 = 5 x 5 = 25 <--- This is our answer!!! 62 = 6 x 6 = 36 <--- Not our answer since 36 > 25
