e^3x=30

OpenStudy (sepeario):

\[\log _{e}30=3x\]

OpenStudy (sepeario):

I think that's the equation... I'm not that familiar with logarithms though.

OpenStudy (anonymous):

It say's solve also, I'm just learning this.

OpenStudy (sepeario):

x = approx. 1.13373246

I need to go, but I can explain to you in like 15 mins.

OpenStudy (anonymous):

Ok.

OpenStudy (aaronandyson):

Is It \[e^3x = 30 ?\]

OpenStudy (sepeario):

Ok here I go. And @AaronAndyson it isn't it says e^3x not (e^3)*x.

OpenStudy (sepeario):

In a logarithm, where a is the base, b is the exponent and c is the product, i.e. a^b=c, it is written in the following format: \[\log _{a}c=b\]

OpenStudy (sepeario):

Which is why when 'e' is the base, 3x is the exponent, and 30 is the product, the logarithm is written as \[\log _{e}30=3x\]

OpenStudy (sepeario):

You can use a calculator to evaluate this, but you may not find log e. This is because this is also known as 'ln' or a natural logarithm; \[\ln product=exponent\]
