Convert the Following expression to the indicated base, using base 14 for a > 0 & a \ne 1.\(\displaystyle {a}^{\frac{5}{log}_{9{}^{a}}}\)

THIS IS WHAT I MEANT! THANKS! though it was trig problem because in class my professor was going over trig...sorry if it was not [/QUOTE]greg1313 said:Hi Teh. I've shortened up the title of your thread.
Did you intend
$a^{5/\log_9a}$
?
Why did you post this in trigonometry?
greg1313 said:I'm still not clear on what's intended. Are we to convert the base 9 log to a base 14 log? If not, what is the "indicated base"?
Teh said:same also I don't know what is is asking for I ask my professor all he gave me was $\log_{b}{x} = \frac{\ln x}{\ln b}$
"Change of base" with logs refers to the process of rewriting a logarithm with a different base. This is often done to simplify calculations or to solve equations.
Changing the base of a logarithm can make it easier to solve equations or perform calculations. It can also help to compare logarithms with different bases.
To change the base of a logarithm, you can use the change of base formula: logb(x) = loga(x) / loga(b). This formula allows you to rewrite a logarithm with base b in terms of a logarithm with base a.
Yes, you can change the base of any logarithm using the change of base formula. However, some bases may be more convenient to work with depending on the problem you are trying to solve.
The only limitation is that the base of the logarithm cannot be zero or negative. This is because the logarithm function is only defined for positive numbers.
