what is the exact solution of e^(x)-2=8 ? In_?_

OpenStudy (freckles):

isolate e^x by adding 2 on both sides then you can take natural log of both sides

OpenStudy (anonymous):

e^(x)=10 then what?

OpenStudy (anonymous):

@freckles ?

OpenStudy (freckles):

did you try taking natural log of both sides as I suggested ?

OpenStudy (anonymous):

idk how to do that

OpenStudy (anonymous):

the teacher gave us this and told us to do it then turn it in tomorrow with answers

OpenStudy (freckles):

do you know how to write an exponential equation an its equivalent log form?

OpenStudy (freckles):

or you can go the other way \[x=b^y \implies \log_b(x)=y \\ \text{ and you have } \\ 10=e^x \implies ?\]
