If H.C.F. of `p` and `q` is `x` and `q=x y` , then the L.C.M. of `p` and `q` is `p q` (b) `q y` (c) `x y` (d) `p y`

If HCF of p and q is x and q = xy , then the LCM of p and q is

If p and q are primes, then H.C.F. (p, q) will be

if the pth term of an A.P.is x and qth term is y, show tht the sum of (p+q) terms is (p+q)/(2)[x+y+((x-y)/(p-q))]

If x # y = (x + y)/(xy) , then the value of P # (q # r) for every p, q, in N :

If x^py^q=(x+y)^(p+q) , then dy/dx= (a) x/y (b) y/x (c) x/(x+y) (d) y/(y+x)

SECTION MULTIPLE CORRECT CHOICE TYPE Example 41 Let a, b, c , p, q be five different non-zero real numbers and x, y, z be three numbers satisfying the system of equations a a-p aq then (a) x + y + z = a + b + c-p-q abc (b) x = pq 0 in (c) y = (a-p)(h-p)(c-p) p(p-q) (a-q)(b-q)(c-q) aq-p) (d) z = b.

In the figure,find x and y if l| I m and p||q

If x=(p+q)/(p-q) and y=(p-q)/(p+q) then the value of (x-y)/(x+y) is
