Question

log(x-3)=2?

Answer 1

First change it to exponential form.
\[10^2 = x - 3\]Can you solve for x?

Answer 2

\[\log (x-3) = 2\]
it is implicit when given this kind of thing that the base is 10 so
\[\log_{10} (x-3) = 2\]
now change to exponential
\[10^2 = x - 3\]
expand
\[100 = x - 3\]
add 3 to both sides
\[100 + 3 = x\]
