x--->infinity


I got no idea with how to do this one. Can anyone please teach me how to do it?????THANKS A LOT!!!

    In this case the term within brackets becomes 3/5 in the limit as x -> infinity, and the square root of 3/5 is 0.774597..

    You posted a similar question later but with a minus sign in front of the 5. That has an imaginary limit
