72
6 root 2 or 8.485281374
√-72 = i√(622) = i6√2
72.0
The square root of 324 is 18 so the perimeter must be 4*18 = 72 cm
6√2
sqrt(72) = 6 sqrt(2)
6√2
sqrt(72) = sqrt(36*2) = sqrt(36)*sqrt(2) = 6*sqrt(2).
Factor under the radical. sqrt(72) sqrt(3^2 * 8) 3sqrt(8) 3sqrt(2^2 * 2) 6sqrt(2) check and you see that sqrt(72) and 6sqrt(2) are equivalent
588 = 22*3*72 so sqrt(588) = sqrt(22*3*72) = 2*7*sqrt(3) or 14*sqrt(3)
Given the phrasing of your question, that could be a matter of debate.First, the square root of 72 is actually 8.48528137, at least that is accurate to within 1/10,000,000th.As far as "simplest" goes, that is the answer.There is a concept of a "simplified radical form" that you may actually mean.If so, the answer is 6 times the square root of 2. This represents the fact of 36 times 2 equalling 72, and six being the square root of 36. The square root of 2 starts out as 1.414 and is by no definition "simple", so we simply say "six times the square root of two" as opposed to "six times 1.414...forever in a non-repeating way".6 root 2
The square root of 72 is equivalent to 6 times the square root of 2.
Well, there technically is not a way to simplify the square root of 2, but the simplified version of the square root of 72 is 6 square root 2
36
6 root(2) = root(36) root(2) = root(36 x 2) = root(72).
