Question

Solve log x = 4. (2 points)


x = 4
x = 40
x = 1,000
x = 10,000

Answer 1

\(\large \log_{{\color{brown}{ }} } {\color{blue}{ x}}=4\implies \log_{{\color{brown}{10 }} } {\color{blue}{ x}}=4\implies {\color{brown}{ 10}}^4={\color{blue}{ x}}\)

Answer 2

you need tp raise both sides of the equation as a power of 10

as it appears you are using base 10 logs

the rule is

\[10^{\log_{10}(a)} = a\]

hope it helps

Answer 3

when the base is omitted, or skipped
keep in mind that, "base 10" is assumed

Answer 4

Oh so it's C then?

Answer 5

well 10^3 = 1000

Answer 6

Ok great, thanks! :)

Answer 7

and you want 10^4 as @jdoe0001 showed you

Answer 8

Oh so it's actually D?

Answer 9

yes
