hi, everyone. So today we need to estimate the square root of the square to 61 and then run to the nearest integer. Well, 61 is in between the square roots of 49 64th visible perfect squares, and 49 the square and 49. A seven and square of 64 is eight. So since the square root of 61 is closer to the squared of 64 it's safe to say that it will be closer to eight, then seven. So I put my calculator the squirt of 61 7.81 exception. So since we need to round, we're going to cut off the decimal and then round. So this round's up to about eight, so the square root of 61 is a approximately eight.
