puteri [66]

Hello from MrBillDoesMath!

Answer:

fourthroot(35)


Discussion:

The question is a bit unclear as to the desired answer.... but here goes!  

(35)^1/4 is the fourth root of 35, that is, symbolically,   fourthroot(35).

Note the fourth root of a number is the same as the square root of the square root of the number.

Regards,  

MrB
