If r, s, t are prime numbers and p, q are the positive integers such that the LCM of p, q is r squared s to the power of 4 t squared, then the number of ordered pair (p, q) is-

Be careful about selecting the r s and t for this particular problem. Because number ways for each selection of r, s and t there are 3 cases. Because there are two values given

p, q . Hence to calculate the total number of ways is to multiply the number of ways for r, number of ways for s and number of ways for t. So, in this way to solve this particular type of problem.
