Lấy logarit 2 vế:
\(ln\left(2^{3x+4}\right)+ln\left(3^{2x+1}\right)=ln\left(5^{x-1}\right)\)
\(\Leftrightarrow\left(3x+4\right)ln2+\left(2x+1\right)ln3-\left(x-1\right)ln5=0\)
\(\Leftrightarrow x\left(3ln2+2ln3-ln5\right)=-\left(ln5+4ln2+ln3\right)\)
\(\Leftrightarrow x=-\frac{ln5+4ln2+ln3}{3ln2+2ln3-ln5}=-\frac{ln\left(5.2^4.3\right)}{ln\left(\frac{2.3^2}{5}\right)}=...\)
