Question 934705

log1.0 X 10^5 = 5.00 

This is from a chemistry textbook. I do not understand how it can equal 5.00. Can someone please explain why and how?
Thanks.
<pre>
{{{log 1 * 10^5 = 5}}}
{{{log 1 + log 10^5 = 5}}}
log 1 = {{{10^0}}}, or 0, while {{{log 10^5}}} = 5
Therefore, {{{log 1 * 10^5 = 5}}} = {{{log 1 + log 10^5 = 5}}} = 0 + 5, or 5
