Question

Please answer 50th with explanation

Answer 1

root(3+root5)=
root5=2.23
root(3+root5) (put here value of root5=2.23)
root(3+2.23)
root(5.23)
=2.29
from options
1st canot be ans it value high than 12
2nd cannot be ans
root(8/2)=2 & root(1/2)=0.71 2nd =2.71
3rd cannot be ans
root(7/2)=1.87 & root(1/2)=0.71 3rd=1.16
4th not be ans
root(9/2)=2.12& root(3/2)=1.22 4th =0.80
therefore ans is correct
