Answer 2

Answer:

2√7/√3+√5

=2√7(√3-√5) /(√3+√5) (√3-√5)

=2√7(√3-√5) /(√3) ²-(√5) ²

=2√7(√3-√5) /3-5

2√7/-2(√3-√5)

=-√7(√3-√5)

=-√21+√35

=√35-√21

that is irrational number because if we substract a irrational number from an another irrational number the resultant no. is also a irrational. so here √35 & √21 both are irrational so the difference also irrational.
