If `P+M=6` and `P^3+M^3` then `PM=`

If P_m stands for ^m P_m , then prove that: 1+1. P_1+2. P_2+3. P_3++ndotP_n=(n+1)!

If P_m stands for ""^mP_m , then : 1+1.P_1+2P_2+3P_3+.........+nP_n is equal to ,

If m+2 , 4m-6 and 3m-2 are three consecutive terms of an A.P., find the value of m.

It is between 3 P.M. and 4 P.M. and the distance between the hour and the minute hand of clock is 18 minute spaces. What time does the clock show? (a) 3.12 P.M. (b) 3.27 P.M. (c) 3.31 P.M. (d) 3.36 P.M.

If p(m) =m^3 +2m^3 -, +10 , then p(a) +p(-a) =?

Find the time between 1 P.M. and 2P.M. when the angle between the hands of a clock is 186(2)/(3) grades.

if .^(m+n)P_(2)=56 and .^(m-n)P_(3)=24 , then (.^(m)P_(3))/(.^(n)P_(2)) equals

If .^(m+n) P_(2)=56 and .^(m-n)P_(3)=24 , then (.^(m)P_(3))/(.^(n)P_(2)) equals
