Express the following in index form
Logx + logy =1
log(xy) = 1
xy = 10
-------------------
Logx =6
x = 10^6 = 1000000
--------------------------
Log (x+4) = log64
log(x+4)/(64) = 0
(x+4)/64 = 1
x+4 = 64
x = 60
------------------
Log (2x+1) - log (3x-2)
---
= log[(2x+1)/(3x-2)]
=======================
Log (3x-1) - log2 = 3
----
log[(3x-1)/2] = 3
----
(3x-1)/2 = 10^3
-----
3x-1 = 2000
3x = 2001
x = 667
