Me solve this problem

3

5+square root 41

Ya want to rationalize the denomenator
if we mutliply the whole thing by (√41)/(√41), we wil still have a √ there messing things up

we need to remember the difference of 2 perfect squares

remember
(a+b)(a-b)=a²-b²

so, we can see the denomenator is 5+√41
multiply the whole fraction by

we get

Dis the correct  answer
