Find `a` and `b` if `(3+sqrt(7))/(3-sqrt(7))=(a+b sqrt(7))`

(i) Find a and b when (3+ sqrt(7)) /(3-sqrt(7))= (a+bsqrt(7))

(3-sqrt7)(3+sqrt7)=?

Find the values of a and b in each of the (sqrt(7)-2)/(sqrt(7)+2)= a sqrt(7)+b

In each of the following determine rational number a\ a n d\ b : (i)\ (3+sqrt(2))/(3-sqrt(2))=a+bsqrt(2) (ii)\ (5+3sqrt(3))/(7+4sqrt(3))=a+bsqrt(3)

If both a\ a n d\ b are rational numbers, find the values of a\ a n d\ b in each of the following equalities: (3+sqrt(7))/(3-sqrt(7))=a+bsqrt(7)

(sqrt(7)+2sqrt(3))(sqrt(7)-2sqrt(3))

In each of the following determine rational number a\ a n d\ b : (i)\ (sqrt(11)-sqrt(7))/(sqrt(11)+\ sqrt(7))=a-bsqrt(77) (ii)\ (4+3sqrt(5))/(4-3sqrt(5))=a+bsqrt(5)

If 0ltxltpi and cosx + sinx =1/2 , then tanx is (1) (4-sqrt(7))/3 (2) -(4+sqrt(7))/3 ( 3) (1+sqrt(7))/4 (4) (1-sqrt(7))/4
