Log3x – log3 (x-5) = log3 A

Express A in terms of x.

Hence, solve the equation

Log3 x – log3 (x-5) = 1

Thank you so much.

oh okay, so next i did

A = x/x-5

and i crossed multiplied to get x = A(x-5)

but for the next part of the problem, i replaced this for x and now i am stuck.

Your help is much appreciated! - Dec 16th 2009, 09:58 PMJhevon
