Limit x tend to infinite under root x bi under root x plus under root x plus under root xPls solve this question step by step.

Under root x/x+x+x+…………… here add one and subtract one It becomes under root (x-x+x+………/x+x+x+…………) +1. As x tends to infinity the part under the bracket becomes one and we will be left with under root 2 and I think that is the answer.
