Practicing Success
Given $p \neq 1$, then $\int \frac{\mathrm{d} x}{x\left(\log _{e} x\right)^{p}}$ is equal to : |
$\frac{\left(\log _{e} x\right)^{1+p}}{1+p}$ $\frac{1+p}{\left(\log _{e} x\right)^{1+p}}$ $\frac{\left(\log _{e} x\right)^{1-p}}{1-p}$ $\frac{1-p}{\left(\log _e x\right)^{1-p}}$ |
$\frac{\left(\log _{e} x\right)^{1-p}}{1-p}$ |
p ≠ 1 , then $I = \int \frac{dx}{x(log ~ x)^p}$ let y = log x dy = $\frac{1}{x}$ dx $\Rightarrow I =\int \frac{1}{y^p} d y$ $=\frac{y^{-p+1}}{-p+1} ≡ \frac{y^{1-p}}{1-p}$ $\Rightarrow I=\frac{(\log x)^{1-p}}{1-p}$ |
