Question

Square of a negative rational number can not be calculated?

Answer 1

Answer:

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+bsqrt(3) (ii) (3+sqrt(7))/(3-sqrt(7))=a+bsqrt(7) (5+2sqrt(3))/(7+4sqrt(3))=a+bsqrt(3) (iv) (5+sqrt(3))/(7-4sqrt(3))=47a+sqrt(3)b (sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))=a+bsqrt(15) (iv) (sqrt(2)+sqrt(3))/(3sqrt(2)-2sqrt(3))=1-bsqrt(3)
