Step-by-step explanation:

u can convert it into root

Answer 2

Step-by-step explanation:

-3/(2-√3)

×by1/(2+√3)

=>-3/(2-√3)×1/(2+√3)

[(a+b)×(a-b)=a²-b²]

→-3/(2)²-(√3)²

=-3/4-3

=-3/1

=-3

3√2/(√6+√3)

×by 1/(√6-√3)

=>3√2/(√6+√3)×1/(√6-√3)

[(a+b)×(a-b)=a²-b²]

→3√2/(√6)²-(√3)²

=3√2/6-3

=3√2/3

take 3 common

→3(1√2/1)

4√3(√6+√2)

Similarly

→4√3/(√6)²-(√2)²

=4√3/6-2

=4√3/4

take 4 common

=4(1√3/1)

Lastly,

-3-3(1√2/1)+4(1√3/1)

upon simplifying↓

-3-3√2/3+4√3/4

-9√2/3+4√3/4

-2√2+4√3/4

taking 2 common

2(-1√2+2√3/2)

*2 gets cancelled*

=-√2+2√3 or 2√3-√2
