If y=x^2(a+z) determine an expression equal to log x. (Hint: you will need to take the log both sides at some point)

Would this property help you?

[tex]\log a^b = b\log a[/tex]

[tex]\log a^b = b\log a[/tex]

Would it be like...

logx = xlog

then xlog^2(a+z)

Sorry I'm really confused/

[tex] \log y = \log x^2^(^a^+^z^)[/tex]

See the similarity between the b in my earlier equation and 2(a+z)? >_>

I did this...

log(y/x) = 2a + 2z

so thats logx = (2(a+z))/y

I'm still stuck

[tex] \log y = \log x^2^(^a^+^z^)[/tex]

[tex] \log x = \frac{\log y}{2(a+z)}[/tex]

Pepsi, please post all coursework related questions in the Homework Help section.

Also, you need to relearn the properties of logarithms first. Please go over this chapter in your text again. For instance, log(y)/log(x) is not the same as log(y/x).
