Question 200797: Hello,
Could someone please help me simplify these logarithms/
1. (log(subscript2)(5))+(log(subscript 2)(x^2-1))-(log(subscript 2)(x-1)
This is what I have so far:
(log(subscript 2)(5)(x^2-1))/(x-1)
2. 3^(2log(subscript 3)(5))
Thank you so much for Your time!

1. (log(subscript2)(5))+(log(subscript 2)(x^2-1))-(log(subscript 2)(x-1)
This is what I have so far:
(log(subscript 2)(5)(x^2-1))/(x-1)
log(2)[5(x+1)]
----------------------------
2. 3^(2log(subscript 3)(5))
=3^[log(3)[5^2]]
=3^[log(3)[25]]
= 25
