Answer 1

Answer:

4@12 - 4@18 - 4@6

Step-by-step explanation:

the question is about rationalizing you should rationalize each denominator and then add or subtract it :)  so you will get the numerator and denominators as

{i m using this symbol as root @ }

2@12 - 2@ 18 / 1

2@12 - 2@6 / 1

2@18 - 2@6 / 1

so as every denominator now is 1 we can evaluate the numerators

it is like (2@12 - 2@18) + (2@12 - 2@6) - ( 2@18 - 2@6 )

= 2@12 - 2@18 + 2@12 - 2@6 - 2|@18 - 2@6

= 4@12 - 4@18 - 4@6

this is the final answer

if you know how to rationalize then you may understand it

i use computer and there is no root sign so i used @ sign
