Question 928299: 1. log2(x-3)=3-log2(x-1) (the base is log 2)
2. 6log7(x^2-1)-5log7(x-1) (the base is log 7)
For the first problem i need to solve it
and for the 2nd problem i need to express it as a single logarithm.
I have been trying to solve this but I am always off on my answers. I need to know how it is solve step by step. Thank you so much.

1. solve it
...in base
...if log. same, then
is same too; so, solve it for
...group
solutions:
if => ...your answer
if => ...reject negative value for log
2. express it as a single logarithm
....since , we will have
