उत्तर

\[\int\]loge x dx
` ∫   1_{II} . log_{e_I   \text{ x   dx } `
 =  \[\log_e x\int1 \text{ dx} - \int\left\{ \frac{d}{dx}\left( \log_e x \right)\int1 \text{ dx} \right\}dx\]
\[\int\]= loge  x   \[\int\] 1 . dx  \[\int\] \[\frac{1}{x} \times x   .   dx\]
= loge x × x – ​\[\int\]dx
=​ x loge x – x + C
=​ x loge x – x + C
x (loge x – 1) + C
