Exponential form - Math Central
Hi Motaz. Let me demonstrate with a similar question:
Let z = log[5] (1/625).
Start by realizing that if the log is in base 5, we want to exponentiate with base 5 on both sides:
5^z = 5^ log[5] (1/625)
On the right hand side, the exponentiation and the log cancel each other, because they... | {"url":"http://mathcentral.uregina.ca/QQ/database/QQ.09.08/h/motaz1.html","timestamp":"2014-04-16T18:56:55Z","content_type":null,"content_length":"7264","record_id":"<urn:uuid:c8e7a483-ff5a-4ae7-b3e8-e27f85f2052a>","cc-path":"CC-MAIN-2014-15/segments/1397609524644.38/warc/CC-MAIN-20140416005204-00207-ip-10-147-4-33.ec2... |

solve for x - WyzAnt Answers
solve for x
Tutors, please
to answer this question.
9/2 log[3](x) = 1
log[3](x) = 2/9
now, to "undo" the log[3] on the left side of the equation, we raise 3 to the power of each side of the equation.
x = 3^(2/9)
x = 1.28, rounded to three digits. | {"url":"http://www.wyzant.com/resources/answers/16087/solve_for_x","timestamp":"2014-04-16T15:21:17Z","content_type":null,"content_length":"40546","record_id":"<urn:uuid:0eedaffd-d85e-4330-88b2-169b8a687fd8>","cc-path":"CC-MAIN-2014-15/segments/1397609523429.20/warc/CC-MAIN-20140416005203-00220-ip-10-147-4-33.ec2.inter... |
