Answer 1

Answer: Hope it will be helpful. N= -1

Step-by-step explanation:

I have followed some steps:

• Check the number under square root whether it forms perfect square or not. I have checked for all but got only (3+ 2*sq root 3) is perfect square.
• Remember sq root(4) =2 only as sq root(4) is positive quantity. But if x= sq root(4) then is + 2 and -2 as x is variable
• Check approx value of N.
