Hi, i need to solve this logarithm
-------------------
If you want to solve for x:
a) log3 x=4
If 3 is the base:
log%283%2Cx%29+=+4
--> x+=+3%5E4
x = 81
========================
b) log10 x=1/2
Use a calculator.
======================
c) log3 (x-1)=1
See a) above.
===================
d) log3,5 (2x²-5x+3)=0
