Answer:
the ans is al
Step-by-step explanation:
3√8/√2
=3(√2x√2√2)/√2
=√2 and √2 will get cancelled from the denominator and one from numerator
which leaves
3x(√2x√2)
=3x2 =6
which is rational
the second one.....according to (a+b) the whole square is also rational
the third one the value would be 1/5..if you divide it giving π value 22/7
fourth can be solved using (a+b)(a-b)....because if you rearrange you will get that easily
Hope this helps
