The number of proper divisor of a^p * b^q * c^r * d^s where a,b,c,d are primes where p,q,r,s are natural number??
(p+1)*(q+1)(r+1)(s+1) - 2 or - 1 is it?
....-2 is correct.pls explain fog856
Total number of divisors - the number itself and 1
Bro u use cengage uh ?
now for revision.. Determinant chapter is too difficult in this..
Ohhok... All the best !
same to u bro..
Fog856 solve these also
Find the total number of positive integral solution of 15<x1 +x2+ x3<=20
Q2.Find the number of integral solution of the eqn x+y+z =-12
As far as question 2 is concerned, i really don't know why answer can't be infinite as long as there are no constraints.
Same Doubt in q2.Anmol I'm not able to understand what u did pls explain in detail
1st question can be done by beggar's method also..try it that way..
Other teachers use that name too? I thought only my sir used that name.
The first solution is itself done by beggar's ...
And @ayush_singh I am not sure where that name came from , but , in case you're from Kota , Sameer Bansal taught that to us saying that the name was given by VK Bansal lol ..
My maths teacher is a big fan of Bansal sir..all the assignments and test in our coaching are from Bansal too..
@Ananya_Singh What is alternative name for beggars method
@Sarju_Panchal1 I don't know my sir has always used that name only..
@Ananya_Singh which coaching u in?
Ans kya h
