If p,q and r are prime numbers such that `r=q+2` and `q=p+2`, then the number of triples of the form `(p,q,r)` is

If p, q, r are prime numbers such that p^(2)-q^(2)=r then which of the following options are correct ?

If r,s,t are prime numbers and p,q are the positive integers such that LCM of p,q is r^(2)s^(4)t^(2) , then the number of ordered pairs (p,q) is:

r, s, t are prime numbers and p, q are natural numbers such that LCM of p, q is r^(2)" "s^(4)" "t^(2) , then the number of ordered pairs (p,q) is

If r,s,t are prime numbers and p,q are the positive integers such that LCM of p,q is r^2t^4s^2 , then find the number of ordered pair (p,q).

lf r, s, t are prime numbers and p, q are the positive integers such that their LCM of p,q is r^2 t^4 s^2, then the numbers of ordered pair of (p, q) is

lf r, s, t are prime numbers and p, q are the positive integers such that their LCM of p,q is r^2 t^4 s^2, then the numbers of ordered pair of (p, q) is
