take logs of both sides
(x+2) log 4 = log 160
x+2 = log160/log4
x = log160/log4 - 2
that is also log4160 - 2
but most calculators don't do logs to various bases, but do have log
Solve 4^(x+2)= 160 use a cal and round your answer to the nearest hundredth
How would I work out this problem? I'm a little confused with this one.
