Question

5-3^x=-40

Answer 1

where are you stuck at? ^_^

Answer 2

Logs are confusing to me. I keep trying.

Answer 3

no problem, so we will use the log-power-reduction-rule
so after we have isolated x, we have
-3^x=-45 or
3^x = 45

the log power rule looks like this:
\[\log(m^n) \rightarrow n*\log(m)\]

Answer 4

x= log(45)/log(3) ?

Answer 5

^_^ nicely done, yep
