b.) log t^2- log f
I'll give medals!!! and Fan!!!

Answer 1

log a + log b = log a*b

USe that property to solve part a

Answer 2

log a - log b = log (a/b)

Use this property to solve part B

Answer 3

so its log xy

Answer 4

\(\normalsize\color{blue}{\log(a)+\log(b)=\log(a\times b)}\)

\(\normalsize\color{green}{\log(a)-\log(b)=\log(a\div b)}\)

\(\normalsize\color{red}{\log(a)\div\log(b)=\log_b(a)}\)

there are more rules
