If `x=5,\ \ y=3` and `z=2` , then `(x(y-z))/(y(x+y+z))=?` (a) `1/6` (b) `1/(30)` (c) `1` (d) `5`

If x y z=0, then find the value of (a^x)^(y z)+(a^y)^(z x)+(a^z)^(x y)= (a)3 (b) 2 (c)1 (d) 0

If 3^(x)=5^(y)=45^(z), then a.(2)/(z)=(1)/(y)-(1)/(x)b(2)/(y)=(1)/(x)-(1)/(z)c*(2)/(x)=(1)/(z)-(1)/(y)dx+y+z=0

If x/((2x+y+z))=y/((x+2y+z))=z/((x+y+2z))=a , then find a if x+y+z!=0 . (a)1/3 (b) 1/4 (c) 1/2 (d) 1/8

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

If a,x,y,z,b are in AP then x+y+z=15 and if a,x,y,z,b are in HP.then (1)/(x)+(1)/(y)+(1)/(z)=(5)/(3). Numbers a,b are

If (1)/(x) : (1)/(y):(1)/(z) = 2 : 3 : 5 , then x : y : z = ?

Find the S.D. between the lines : (i) (x)/(2) = (y)/(-3) = (z)/(1) and (x -2)/(3) = (y - 1)/(-5) = (z + 4)/(2) (ii) (x -1)/(2) = (y - 2)/(3) = (z - 3)/(2) and (x + 1)/(3) = (y - 1)/(2) = (z - 1)/(5) (iii) (x + 1)/(7) = (y + 1)/(-6) = (z + 1)/(1) and (x -3)/(1) = (y -5)/(-2) = (z - 7)/(1) (iv) (x - 3)/(3) = (y - 8)/(-1) = (z-3)/(1) and (x + 3)/(-3) = (y +7)/(2) = (z -6)/(4) .
