Answer:

square root of 55 is closer to 7 than to 8

Step-by-step explanation:

Compare 55 with the closest integers that are perfect squares. These are:

below 55 the nearest perfect square is 49 = 7^2

and above, the nearest integer is 64 = 8^2

How close to 49 is 55?  55 - 49 = 6 units

How close to 64 is 55?  64 - 55 = 9 units

So since 55 is closer to 49, its square root is going to be closer to 7 than to 8.
