Question

Please solve this question any expert I need correct answer!!!

Answer 1

Step-by-step explanation:

1) Given:q=√5+2

to find : q+1/q

√5+2+1/√5+2

then cross multipling

=(√5+2)^2+1/√5+2

=25+4+1√5+2

=30/√5+2

2)Give: 3/4√3

taking conjugate

=3/4√3×-4√3/-4√3

=-12√3/(-4√3)^2

=12√3/(16+3)

=12√3/21

Answer 2

2nd question

Answer:

-3(4-3√3) /11

Step-by-step explanation:

3/4-3√3

=3(4+3√3)/(4+3√3)(4+3√3)

=3(4+3√3)/((4)^2-(3√3)^2)

=3(4+3√3)/(16-26)

=-3(4+3√3)/11
