Question

what if we 3√3-4=??????

Answer 1

Hey
The result would be nothing as a number with an under root can be subtracted or added to another under root only if the number lying under the root is same.
Hope it helps :)

Answer 2

hey dear your answer is here:-

u think this is correct answer
3√3-4
= 3√3-√4
= 3(√3)-(√2 ) whole square
now square and root gets cancelled
3√3-2
= 3√1

hope it helps
