WebBy prime factorisation, we get; 400 = 2 x 2 x 2 x 2 x 5 x 5. Now pairing the common numbers in a pair of two, we see here three pairs. Two pairs of 2 and one pair of 5. Therefore, √400 = √ (2 x 2 x 2 x 2 x 5 x 5) Taking out the numbers in pairs. √400 = 2 x 2 x 5 = 20. Hence, the square root of 400 is 20. WebThe square root of 36 is expressed as √36 in the radical form and as (36) ½ or (36) 0.5 in the exponent form. The square root of 36 is 6. It is the positive solution of the equation x 2 = 36. The number 36 is a perfect square. …
