I'm having trouble with logarithms?

Question

Express each expression as a single logarithm. Simplify if possible.

1.) log(log7(98)-log7(2))^x

 

2.) log4(5)+log4(12)-log4(3.75)

 

 

For number one I got x=0 and for number two I got 1. I think I did it wrong though..

Answer 1

1) log₇98 - log₇2^x,,

    log₇ (98/2^x)

 

2) log₄5 + log₄12 - log₄3.75,

    log₄ (5 · 12) / 3.75,

    log₄ 16,
