The write answer will be 8 root 3
I want to know how to solve it
I am a LOT of confused in this
x =7 + 4 root 3 then 1/x = 1/7+4 root 3 rationalise the value of 1/x you will get 7 - 4 root 3 now place the value that is (7+ 4 root 3 ) - ( 7 - 4 root 3 ) you will get the answer 8 root 3
This may help you
