- 12 because N=A*A*B*C;N=A^2*B*C=(2+1)(1+1)(1+1);=12

- 12
This is because the number of factors is (a1+1)*(a2+1)*(a3+1)..... where a1 is the power of the first prime in the prime factorization of the number and so on - 5 years agoHelpfull: Yes(1) No(0)
- All three statement are TRUE
- 5 years agoHelpfull: Yes(0) No(6)
- (2+1)(1+1)(1+1)
=3*2*2=12 - 5 years agoHelpfull: Yes(0) No(0)
- We have a formula
p1^a1.p2^a2,p3^a3..............pn^an=(a1+1)(a2+1)..........(an+1)
therefor (2+2)(1+1)(1+1)=12 - 3 years agoHelpfull: Yes(0) No(0)
