80 = 5 x 4 x 4

they have 4 flavors of icecream

you get this by multiplying all the variables and how many different possibilities each variable can be

so,
5 different syrups (5)
4 different candy toppings (4)

from that you know 5 x 4 x ? = 80

so 5 x 4 = 20, and 20 x 4 = 80

so 4 different flavors of ice cream (4)

How to integrate ∫㏑x/χ<br> from 1 to e

Natali [406]

$\int_1^e\dfrac{\ln x}{x}dx,~\text{if}~u=\ln x\to x=e^u\to dx=e^udu\\\\\text{So, finding the new limits:}\begin{cases}x=1\to u=\ln1\to u=0\\x=e\to u=\ln e\to u=1\end{cases}\\\\
\int_1^e\dfrac{\ln x}{x}dx=\int_0^1\dfrac{u}{e^u}e^udu=\int_0^1u\,du=\left[\dfrac{u^2}{2}\right]_0^1=\dfrac{1^2}{2}-\dfrac{0^2}{2}=\dfrac{1}{2}\\\\
\boxed{\int_1^e\dfrac{\ln x}{x}dx=\dfrac{1}{2}}$
