When a radical is not a perfect square (1, 4, 9, 16, 25), estimating square roots is a valuable tool. When asked to estimate the value of a radical between two consecutive integers, find the two perfect squares that are slightly less and slightly more than the radicand. Also, remember that negative numbers do not have a real number square root.

Examples:

√15, √60, √90, √124, √184
