In Little League the bases are squares with sides of 14 inches. The expression √ (S to the 2nd power + S to the 2nd power) represents the distance diagonally across a square of side length S. Estimate the diagonal distance across a base to the nearest inch.

Simply substitute 14 in place of S in the equation: âš (14 to the 2nd power + 14 to the 2nd power) or âš (14^2 + 14^2) Next, multiply 14 by itself to get 196, and replace both of the 14 to the 2nd powers: âš (196 + 196) Now add to get 392: âš (392) Finally, take the root and round: 20 inches
