Solve: -3 = log3^x

OpenStudy (anonymous):

first, take the antilog of both sides. What do you get?

OpenStudy (anonymous):

what do u mean antlog

OpenStudy (anonymous):

y=log x to get rid of the "log", we take the following step:\[10^y=x\]This is what is meant by the antilog. It "undoes" the log function.

OpenStudy (anonymous):

so there is no solution

OpenStudy (anonymous):

show your steps?

OpenStudy (anonymous):

actually I didn;'t see the exponent on your question. It is even easier. If you have\[\log_{}a^x=x \log_{}a \]by the property of the logarithm. so you should be able to solve yours for x quite readily.

OpenStudy (zzr0ck3r):

what is log3^x? log_3(x) or log_10(3^x) or ln(3^x)???

OpenStudy (anonymous):

log3^x?=4.77

OpenStudy (zzr0ck3r):

what? how can x equal something, what is the base of your log?

OpenStudy (anonymous):

3

OpenStudy (zzr0ck3r):

\[\log_{3}(x)? \]

OpenStudy (anonymous):

I was assuming the question was\[\log_{10}3^x=-3 \]

OpenStudy (zzr0ck3r):

1/27 = x

OpenStudy (zzr0ck3r):

log_3(x) = -3 3^(-3) = x 1/27 = x

OpenStudy (zzr0ck3r):

only use ^ for exponents. Its very confusing.

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so x=1/27

OpenStudy (zzr0ck3r):

yes
