Question

(I don't usually ask for help on Brainly, but I really suck at Radicals and I need help.

Answer 1

The answer is C (give the other guy brainliest please !!)

Answer 2

My first answer.  Lots of parts for five minutes. Took me that long to decode the question.  It looks like your multiplying where you're taking roots.


$(\sqrt[4]{7})^5 = (7^{\frac 1 4})^5 = 7^{\frac 5 4}$

Choice A.  Next

$(3^{2/3})^{1/6} = 3^{ \frac 2 3 \times \frac 1 6 } = 3^{\frac 1 9} = \sqrt[9]{ 3}$

Choice B. 

$\dfrac {2^{3/4} } {2 ^{1/2} } = 2^{3/4 - 1/2} = 2^{1/4} = \sqrt[4] {2}$


Choice C
