5V2 is the square root of 50, not 82. The only connection between 50 and 82 is that they are both 1 more than a perfect square (49 and 81).
You could express V82 as V41 x V2

Since the prime factorization of 82 is 2 * 41, where * means multiply, it is true that
sqrt(82) = sqrt(2) * sqrt(41)
However, 5 * sqrt(2) = sqrt( 5*5 *2) = sqrt(50), which can't be the same as sqrt(82).
Approximate values (from Microsoft Excel) are:
sqrt(82) = 9.05538513813742
5 * sqrt(2) = sqrt(50) = 7.07106781186548

No, 5 doesn't go into 82 an even # of times, it is, well, just the square root of 82, i can't think of any other way to put it.

sqrt(82) = sqrt(2 * 41)
since neither the 2 or 41 can be square rooted, you get sqrt(82)
by the way, 5V2 = sqrt(25 * 2) = sqrt(50)

5v2 = v(2 x 5 x 5)
= v50
(v49 = 7 so the answer would be just slightly higher than 7)
which clearly isn't the same as v82
but we do know that v81 = 9 precisely so the answer would be slightly higher than 9
so the two are not equivalent

no...
82 = 2 x 41
41 is prime
V82 = 9.05538...
5V2 = 7.07106...

5*sqrt(2) = sqrt (5^2 * 2) = sqrt(50) =/= sqrt(82)
They are not the same.

V82 is 9.055385138 and is not 5V2

sguare root of 82= 9.055
5V2 =4.472
it can be equal to 5V4.05 :D

no sqr 82 = 9.055
5 * sqr 2 = 7.071
They don't have calculators where you live?
