Since 13 is not a square number there is no exact real answer, but you can find an approximate value using the following (Newton-Raphson) iteration formula: xn+1=x n - (x2n -13)/(2xn). Using this formula the square root of 13 can be stated as 3.605551275 to 10 s.f. after 3 iterations starting from 3.5.
1 The expression becomes the square root of 9 times the square root of 2 times the square root of 6. 2  Rewrite the square root of 9 in its simplest form; the square root of 9 equals 3. 3  Your expression should now read 3 times the square root of 2 times the square root of 6.ultiply the radicands. For instance, the square root of 5 times the square root of 15 equals the square root of 75 because 5 * 15 = 75. 4. Simplify the radicands to remove any factors that are perfect squares.
