Question 1031459: Can you please show me the steps on how to solve log(z+5) = 8 Found 2 solutions by Boreal, Edwin McCravy:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! log (z+5)=8
raise everything to the 10th power
z+5=10^8
z=10^8-5
==============
or is it log z +5=8
log z=3
z=10^3=1000
Notice that the parentheses matter.
When the base of the logarithm is not written, it is
understood to be 10. So the given problem is:
Learn the principle of equivalent
logarithm and exponential equations:
is equivalent to
Use that principle to change the logarithm form to the
exponential:
