solve \[u^25u+6=0\] by factoring, then replace \(u\) by \(5^x\) and solve for \(x\)

\[u^25u+6=0\] \[(u2)(u3)=0\] \[u=2,u=3\] \[5^x=2\iff x=\log_5(2)\] \[5^x=3\iff x=\log_5(3)\]

when i got (u2)(u3)=0 i did u=2, u=3 \[3^x=3,3^x=2\]\[x=1,x=\log(2)/\log(3)\]

well i am an idiot, it said \(3^x\) not \(5^x\) so i screwed up it should be \(3^x=3\) so \(x=1\) or \[3^x=2\] so \(x=\frac{\ln(2)}{\ln(3)}\)
