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`

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.

If x^p y^q= (x+y)^(p+q) , then prove that dy/dx = y/x

H.C.F and L.C.M of two numbers x and y is P & Q respectively, then x xx y = ……………….?

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

If x^p . y^q = (x + y)^(p + q) , show that (dy)/(dx) = y/x

If x^p y^q = (x+y)^(p+q) , then( d^2y)/(d x^2 ) =..........

If |[a, p, x],[ b, q, y], [c, r, z]|=16 , then the value of |[p+x, a+x, a+p], [q+y ,b+y, b+q],[ x+z, c+z, c+r]| is 4 (b) 8 (c) 16 (d) 32

If (p)/(x) +(q)/(y) =m and (q)/(x) +(p)/(y) =n , then what is (x)/(y) equal to ?
