hi all,

Find for

i then try to get this result from first principles:

then cancel the fractional powers by raising both numerator and denominator by reciprocal power, so that

what am i doing wrong?

thanks sammy.

. To find the limit, we rationalize the numerator

thanks a lot for that (Clapping).
