Answer 2

Answer:-2√3-√75-√45/16

Step-by-step explanation:2/√5+√3+2

let √5+√3 be a

2/a+2

2/a+2 * a-2/a-2

2a-4/a^2 - 4

putting the value

2(√5+√3) - 4/(√5+√3)^2 - 4

2√5+2√3 - 4/ 5+3+2√15 - 4

2√5+2√3 - 4/ 4+2√15

4-2√15(2√5+2√3-4)/4^2- 2√15^2

8√5+8√3-16+4√75+4√45-8√5/16-60

8√3-16+4√75+4√45/-64

4(2√3+√75+√45)/-64          TAKING 4 COMMON

2√3+√75+√45/-16
