SOLUTION: 1. Solve the following equations a) log(base 5)x+2 + log(base 5) x-2 - log(base 5)4 = log(base 5)3 b) log(base 5)x^2-4 - log(base 5)4 = log(base 5)3 c) log(base 5)x+2 = 1- log(b

Question 744484: 1. Solve the following equations
a) log(base 5)x+2 + log(base 5) x-2 - log(base 5)4 = log(base 5)3
b) log(base 5)x^2-4 - log(base 5)4 = log(base 5)3
c) log(base 5)x+2 = 1- log(base 5) x-2
d) log(base 5) (x^2-4) =1
Can you please help me out? Thanks so much in advance:)
Can you please show all the steps it would really help me understand:)

log(base 5)x+2 + log(base 5) x-2 - log(base 5)4 = log(base 5)3

log(base 5)((x+2)(x-2)) - log(base 5)4 = log(base 5)3

log(base 5)(((x+2)(x-2))/4) = log(base 5)3

common base

x=+/-4
therefore x=4
