1.} 2÷√3-√5
2.}. √3±√2÷√3-√2
3.}. 6÷√5+√2
4.}. 4÷√7-√3
5.} 1÷5+3√2

Answer 1

2. =√3+√5. / (√3-√5 )* (√3-√5) {The denominatr is rationalized by this formula the sign always change from add to subtarctn and vice versa}

2√3+2√5 / (√3)²+(√5)²

2(√3+√5) / 3½*² + 5½*²

2(√3+√5) /3+5

2(√3+√5) /8

4(√3+√5). {the 8 is divided by 2 that is common in both root3 and root5}

4√3+4√5
