Its actually the same length. I will choose B so that i can run slower
we are given
![\frac{\sqrt[3]{7}\sqrt{7}}{\sqrt[6]{7^5}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Csqrt%5B3%5D%7B7%7D%5Csqrt%7B7%7D%7D%7B%5Csqrt%5B6%5D%7B7%5E5%7D%7D%20%20%20%20%20)
we can write it in terms of exponents

Firstly , we will simplify numerator

now, we can add exponents

we can cancel it
and we get
