If `HCF(16,y)=8`and `LCM(16,y)=48,` then the value of `y` is

If log_(y)x=8" and "log_(10y)16x=4 , then find the value of y.

Let S be the set of all ordered pairs (x,y) of positive intergers, with HCF (x,y)=16 and LCM (x,y) = 48000. The number of elements in S is

If x-y=9 and xy=16 then the value of x^(2)+y^(2)

If x^(y). y^(x)=16 , then the value of (dy)/(dx) at (2, 2) is

If x^(y). y^(x)=16 , then the value of (dy)/(dx) at (2, 2) is

If xprop y and y =8 when x =2, if y=16 , then the value of x is

Let vertices of the triangle ABC is A(0,0),B(0,1) and C(x,y) and perimeter is 4 then the locus of C is : (A)9x^(2)+8y^(2)+8y=16(B)8x^(2)+9y^(2)+9y=16(C)9x^(2)+9y^(2)+9y=16(D)8x^(2)+9y^(2)-9x=16

If x+y=8 , then the maximum value of x y is (a) 8 (b) 16 (c) 20 (d) 24
