Question

Solve the following question
4√2-2√8+(3/√2) is equal to?

Answer 1

4√2 -2√8+3/√2     here we'll take the l.c.m =√2

now the new ques will become 4 *2 - 2*2*√2*√2+3/√2
8-8+3/√2
=0+3/√2 
so the ans is 3/√2    the answer i gave you is correct you just have to rationalize it 
3/√2*√2/√2
3√2/2   
the previous ans was 3÷√2  
i rationalized it by multiplying and dividing it by √2
3÷√2  ×√2÷√2
=(3×√2)÷ √2*√2
3√2÷2    as √2×√2 is=2
