Question 1012180

Evaluate each expression without using a calculator.
a) log 1000
b) log 1
c) log2 + log 50
<pre>No base signifies base 10, which is the number system we use.
Let log 1,000 be a
Then we get: {{{log (10, 1000) = a}}} -------> {{{log (10, 10^3) = a}}}
{{{10^a  = 10^3}}} ----- Converting to LOGARITHMIC form
a, or {{{highlight_green(log (1000) = 3)}}}

Same concept for the others.
