When the square root of a number is squared, the result is the original number. Since 42=16 4 2 = 16 , the square root of 16 is 4 .
Is Square Root 16 a SURD?
In general: To simplify a surd, write the number under the root sign as the product of two factors, one of which is the largest perfect square. Note that the factor 16 is the largest perfect square. Recall that the numbers 1, 4, 9, 16, 25, 36, 49, are perfect squares.
√-16 = 4 i Note: since negative times negative equals positive, one could therefore conclude that -4 i is also a correct answer to the square root of negative 16.
