The root

can be converted into the power

. Therefore we can rewrite the problem as

and then follow the exponent rules about a power to a power, multiplying 1/2 and 3/4 together.
Thus the problem becomes

, which then can be turned into
![\sqrt[8]{10} ^{3x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B10%7D%20%5E%7B3x%7D)
, making the last option our answer.

Hey there! :D
In the fraction 1/8, the denominator is 8. There are 8 of these parts or “fractions” in 1. So, multiply that by 25.
8*25= 200
There are 200 1/8s in 25.
I hope this helps!
