How do I solve #log_2 7 = log_2 (7/16)#?
I'm not sure if what I'm doing is correct, but I tried expanding it:
#log_2 7 - log_2 7 - log_2 16#
#= log_2 (7/7) - log_2 16#
#=log_2 1 - log_2 16#
#= log_2 (1/16)#
#=log_2 (1/2^4)#
and after that I just got stuck. Can someone help?

The way you did it is almost correct except you forgot to multiply by -1 after expanding
Remember, you are taking the negative of
You know that
Well,
