Answer» To solve the question, proceed in the following manner- Let a and b be those two roots of the given equations. √(p/q) + √(q/p) + √(n/l) can be written as, √p/√q + √q/√p + √n/√l = (√p²+ √q²)/(√p*√q) + √n/√l = (p + q)/(√p*√q) + √n/√l ...................(1) Given thata : b = p : q Let a = px, b = qx a + b = -n/l ⇒px + qx = -n/l ⇒(p + q)x = -n/l ⇒p + q = -n/lx .............(2) Also a*b = n/l ⇒px * qx = n/l ⇒pq*x²= n/l ⇒√pq * x = √(n/l) ⇒√pq = √(n/l)/x ..........(3) Now from equation 1, (-n/lx)/(√(n/l)/x) + √(n/l) = (-n/l)/(√(n/l)) + √(n/l) = -√(n/l) + √(n/l) = 0 So,√(p/q) + √(q/p) + √(n/l) = 0 |
