evaluate log3 27

OpenStudy (anonymous):

3 is right under log in small printing and there is a space between 3 and 27

OpenStudy (ranga):

\[\Large \log_{b} (P) = Q \quad means \quad P = b^Q\]

OpenStudy (anonymous):

??

OpenStudy (anonymous):

that doesn't really answer the question

OpenStudy (ranga):

\[\Large \text {Let} \quad \log_{3} 27 = x. \quad Then \quad 27 = 3^x\]

OpenStudy (ranga):

You need to solve for x. 27 = 3 x 3 x 3 = 3^3

OpenStudy (ranga):

\[\Large 3^3 = 3^x\]

OpenStudy (anonymous):

thank you

OpenStudy (ranga):

The bases are the same and therefore the exponents must be the same. x = 3. You are welcome.
