Question

Solve log x = 3.

x = 3

x = 30

x = 1,000

x = 10,000

Answer 1

Answer 2

\(\bf log(x)=3\implies log_{10}(x)=3\implies 10^3=x\)

Answer 3

recall that \(\bf \Large log_ab=c\implies a^c=b\)

Answer 4

Where are you getting the 10 from?

Answer 5

\(\bf \Large log_{base}(value)\) when the base is not explicitly written in, base 10 is implied

Answer 6

implied = assumed, right?

Answer 7

yes

Answer 8

Ok, I'm putting that in my notes to remember :-) Thank you @jdoe0001

Answer 9

if you look at your calculator, it has a button that only says [Log], shows no base, takes no base arguments, thus is base 10, really means \(\bf \Large [Log_{10}]\)
