Question 436733: okay, my teacher told us to read our book and do problems on the properties of logarithms. i tried to read and understand but im very confused. one problem asked to use +log+%28+5%2C+2+%29+ ~ 0.4307 and +log+%28+5%2C+3+%29+ ~ 0.6826 to solve these following equations. i need to solve these problems. +log+%28+5%2C+2%2F3+%29+ and +log+%28+5%2C+10%2F9+%29+ thank you very much.

adding logarithms is analogous to multiplying quantities; while subtracting logarithms is analogous to dividing quantities

log5(2/3) = [log5(2)] - [log5(3)]

log5(10/9) = log5[(5*2)/(3^2)] = [log5(5)] + [log5(2)] - {2[log5(3)]}
