Answer 1

\[\log(x)=y\iff 10^y=x\]

Answer 2

Convert to exponential form and then solve. The base of the log is understood to be 10.

\[10^3=2x+3\]

Answer 3

start with \[2x+3=10^3\] and solve for \(x\)

Answer 4

you should be able to go from
\[\log_b(x)=y\] to \[b^y=x\] and back quickly
when you don't see a base, it is assumed to be ten

Answer 5

ok then...
