In the solution, why is it assumed that A,C>0 ? We can get B=1 even when both A,C<0. This way the number of total solutions possible is 16. Can someone help me with this?

Question

Answer 1

Hi Akash,
As the logarithms of negative numbers are not defined, we can conclude that A,C are greater than 0.
Do go through the CAT formulas in Logarithms and Surds to know more.
