Please help me to simplify this expression. . .
I actually worked it to the point I got:
The original equation is
121^(1/5)Can you show me or tell me how to solve this to where there is no rational # on bottom?
. . . . .
In your case, this means that the original expression simplifies as , as you mention.
Now you need to rationalize the radical denominator.
Hint: To be able to take the 121 out of the radical (the fifth root that is indicated by the one-fifth power), you need four more copies of 121 inside the root. So what should you multiply by?
