Substitute $u=\ln x$ , so that $\mathrm du=\dfrac{\mathrm dx}x$ . The integral is then equivalent to

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\int\frac{\mathrm du}{u^p}=\begin{cases}\dfrac{u^{p+1}}{p+1}+C&\text{for }p\neq1\\\\\ln|u|+C&\text{for }p=1\end{cases}$

Then transforming back to $x$ gives

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\begin{cases}\dfrac{\ln^{p+1}x}{p+1}+C&\text{for }p\neq1\\\\\ln|\ln x|+C&\text{for }p=1\end{cases}$

Help please its percents ! I need

harina [27]

X % = x/100 as a fraction
so 0.75 % = 0.75 / 100 = 75/10000 or 0.0075

so 0.75% of 560 = 560 * 0.0075 = 4.2
George was correct.

In a class room 3/10 of the students are wearing blue shirts and 3/5 are wearing white shirts there are 20 students In The class

shtirl [24]

Total number of students in the class = 36

Number of students wearing blue shirts = (1/6) * 36

= 36/6

= 6

Number of students wearing white shirts = (2/3) * 36

= 2 * 12

= 24

Then

Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)

= 36 - 30

= 6

So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
