As in your last step we will do: -1 will be multiplied to the numerator making 1 -ve and root 4 +ve. Then 1- root 4 i.e. 1-2 and answer is -1
Answer will be -1
I am not sure about it
the numerator and denominator - will get cancelled...
thats y its better to write the denominator with fist greatest and then smallest. this helps to get rid of sign complexity
1+2 = 2+1 iseliye
tumhare answer 3 bhi galat hai
