The answer is 1.) 6^1/6


The third root of something is the same as an exponent to the 1/3 power.

(When an exponent is a fraction, the numerator is powers and the denominator finds the root. For example: 3 to the power of 4/2 is multiplied by itself 4 times (81) then the denominator, 2, means we find the square root of it (9). 4/2=2, and 3 to the 2nd power is also 9.)

So that would be 6 to the 1/3 power, then you find the square root of that, so it's (6 to the 1/3 power) to the 1/2 power, and according to the Power Rule (a power on top of a power means you multiply the two powers), that would end up being 1/6.

\sqrt{  \sqrt[3]{6}  }  =  \sqrt{ {6}^{ \frac{1}{3} } }  = (6 { \frac{1}{3} })^{ \frac{1}{2} }  =  {6}^{ \frac{1}{3}  \times  \frac{1}{2} }  =  {6}^{ \frac{1}{6} }
