12.Rationalise and find the value of'`"a'" and "'b'"` ; (i) `"(sqrt(3)-1)/(sqrt(3)+1)=a+b sqrt(3),` (ii) `(sqrt(5)-2)/(sqrt(5)+2)=a+b sqrt(5)`

Find the value of a and b if (i)(sqrt(3)+1)/(sqrt(3)-1)=a+bsqrt(3)" "(ii)(5+2sqrt(3))/(5-2sqrt(3))=a+bsqrt(3)

Find the value of a and b if (i)(sqrt(3)+1)/(sqrt(3)-1)=a+bsqrt(3)" "(ii)(5+2sqrt(3))/(5-2sqrt(3))=a+bsqrt(3)

Find the values of a and b in each of the (5+3sqrt(2))/(5-3sqrt(2))= a+b sqrt(2)

If both a and b are rational numbers,find the values of a and b in each of the following equalities :(sqrt(3)-1)/(sqrt(3)+1)=a+b sqrt(3)( ii) (3+sqrt(7))/(3-sqrt(7))=a+b sqrt(7)(5+2sqrt(3))/(7+4sqrt(3))=a+b sqrt(3)( iv) (5+sqrt(3))/(7-sqrt(3))=47a+sqrt(3)b(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))=a+b sqrt(15) (iv) (sqrt(2)+sqrt(3))/(3sqrt(2)-2sqrt(3))=1-b sqrt(3)

If both a and b are rational numbers;find the values of a and b in each of the following equalities ( i (sqrt(3)-1)/(sqrt(3)+1)=a+b sqrt(3)( ii) (5+2sqrt(3))/(7+4sqrt(3))=a+b sqrt(3)

Find the values of a and b . If (2sqrt6-sqrt5)/( 3sqrt5-2sqrt6)= a +b sqrt(30 )

Find the value of a and b in each of the following :(5+2sqrt(3))/(7+4sqrt(3))=a-b sqrt(3)

If both a and b are rational numbers then find the value of a and b in each of the following (a) (3+sqrt(5))/(3-sqrt(5))=a+b sqrt(5)(b)(3+2sqrt(3))/(5-2sqrt(3))=a+b sqrt(3)

(1)/(2sqrt(5)-sqrt(3))-(2sqrt(5)+sqrt(3))/(2sqrt(5)+sqrt(3)) =

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