If anything wasn't a whole number, the Pythagoreans would have nothing to do with it.
root 8 = root 4 x root 2 = 2 root 2, root 18 = root 9 x root 2 = 3 root 2; 2 root 2 x 3 root 2 = 6 x 2 = 12
6 root(2) = root(36) root(2) = root(36 x 2) = root(72).
5 root 2
The square root of the square root of 2
I will use "root" as a symbol for square root. I assume you want to get rid of the square root in the denominator; this will usually bring some square root into the numerator.If you have the square root by itself, or as a factor, multiply numerator and denominator by this square root. Example:3 / root(2) = 3 x root(2) / root(2) x root(2) = 3 x root(2) / 2.If the square root is added or subtracted with something else, multiply with a "complement", as in the following example:1 / root(2) + 5The "complement" is the same expression, but changing the plus sign to a minus sign. Multiply numerator and denominator aby root(2) - 5:root(2) - 5 / (root(2) + 5)(root(2) - 5)= (root(2) - 5) / (2 - 25)= (root(2) - 5) / -23= -(root(2) - 5) / 23
2 square root 2
The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8
To get the square root of 8, you have to multiply the root of 2 and the root of 4. The root of 4 then simplifies to 2, so the square root of 8 equals 2 times the square root of 2.
The square root of 4 is 2 The cube root of 8 is 2 The quartic root of 16 is 2 The quantic root of 32 is 2 The 6th root of 64 is 2
The cubed root of 2, or 21/3, is equal to 1.259921 The square root of 2, or 21/2, is equal to 1.414214
The cube root of 8 is 2.
