Hello! how would i do this question? will you me?

You would divide out the 171 with something that you would multiply to get that number

Breakdown the 171 by dividing by lowest prime number that it is divisible by:
171/3 = 57
57/3 = 19
3sqrt19
You can't take the sqrt of c so it will stay under the radical.
Sqrt d^2 = d

Putting it all together you get 3dsqrt19c

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
