Well, clearly x = 1 is a solution, yes?
Did you mean: 5^x=4^(x+1)
yes

The you could also write :\[5^x=4^{x+1} \Leftrightarrow 5^x=4^x \cdot 4^1 \]
yes to \[ 5^x = 4^{x+1} \] ?
Now you can divide by 4^x
And use \[\frac{ a^x }{ b^x }=\left( \frac{ a }{ b } \right)^x\]
|dw:1359924788627:dw|
Alternatively, take the natural log of both sides and you have \[ \ln 5^x = \ln 4^{x+1} \] \[ x \ln 5 = (x+1) \ln 4 \] Now solve for x.
i got to this part
@JamesJ that is where my problem is solvinf for that x :D
So subtracting ln 4 . x from both sides, we have \[ (\ln 5 - \ln 4)x = \ln 4 \] Yes? Now take it from there ...
I did the following: \[5^x=4^x \cdot 4 \Leftrightarrow \left( \frac{ 5 }{ 4 } \right)^x=4\]\[x=\log_{\frac{ 5 }{ 4 }} 4=\frac{ \ln4 }{ \ln \frac{ 5 }{ 4 } }=\frac{ \ln 4 }{ \ln5-\ln4 }\]
@JamesJ: sorry, didn't mean to give it away...
thank you every1 for ur help
