Step 1

Refer to the question we have to find the value of M and N for the given conditions.

For solve the first condition wich is given for expressio should be perfect square  and the expression is as,

Step 2

Now for greatest integer value of M<30 the expression M!(M+1)!/2  should be a perfect square.

Step 3

Now since (M!)^2 will always be perfect square so The value of M will depend on (M+1)/2 this term should be such that it is perfect square then only whole te...
