SOLUTION: Solve and check a) 1og(base 7)(x+4) + log(base 7)(x-2) = 1 b) log(base 2)(2m+4) - log(base 2)(m-1) = 3 Can you please help me out? Thanks so much in advance Can you also show

Question 747370: Solve and check
a) 1og(base 7)(x+4) + log(base 7)(x-2) = 1
b) log(base 2)(2m+4) - log(base 2)(m-1) = 3
Can you please help me out? Thanks so much in advance
Can you also show me the steps it would really help me understand:)

....in base we will have

....write as
....group

solutions:
=>
=> ....we do not need this solution since we deal with a logarithm

so, solution to your problem is:

b.
