Answer» Let root 5 be a rational number (where p and q are integer and q is not equal to zero and also p and q have no common factor)So root 5=p/q 5=p2/q2 P2=5q2 So p is a multiple of 5 So p= 5k So putting the in eq 1 we get Q2=5 So q is a multiple of 5 Since p and q have common factor which contradict our statement. So root 5 is a rational number. Yup Yes |
