If `x\ a n d\ y` are two co-primes, then their LCM is `x y` (b) `x+y` (c) `x/y` (d) 1

If x and y are any two co-prime, then their L.C.M. is

If x\ a n d\ y are two co-primes, then their LCM is (a) x y (b) x+y (c) x/y (d) 1

If x and y are two co-primes,then their LCM is xy(b)x+y(c)(x)/(y) (d) 1

If x\ a n d\ y are co-primes, then their LCM is (a)1 (b) x/y (c) x y (d) None of these

If x and y are co-primes,then their LCM is 1 (b) (x)/(y) (c) xy (d) None of these

The product of x\ a n d\ y is decreased by 4 is written as (a) 4-x y (b) x\ (y-4) (c) x y-4 (d) x y+4

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

The quotient of x\ b y\ y added to the product of x\ a n d\ y is written as (a) x/y+x y (b) y/x+\ x y (c) (x y+x)/y (d) (x y+y)/x

If a^x=b ,\ b^y=c\ a n d\ c^z=a , prove that x y z=1
