If $h$ divides $|G|$, not necessary that $G$ has a subgroup of order $h$

if $h$ divides $\# G$, then it is not necessarily that $G$ has a subgroup of size $h$ which can be related to Lagrange Theorem $[G:H]=\frac{\#G}{\# H}$ in the case when the subgroup exists, however it is not generally true such as in the case of…

Quadrilaterals and figures

$ABC$ is a triangle in which $L$ is the midpoint of $AB$ and $N$ is a point on $AC$ such that $AN =2CN$. A line thought $L$ parallel to $BN$ meets $AC$ at $M$ prove that $AM=CN$.

Why can neither GeoGebra, nor MathWay solve this simple math problem?

$\frac{e^{0.75}}{-0.5^e+10000}$ This doesn't work either: $\frac{2.72^{0.75}}{-0.5^{2.72}+10000}$ I can even solve it with a calculator.

Given number n. Find the n digit numbers.

For eg; if n = 2, Then the output should be 10,11,...99 // (i.e) 10 to 99 if n = 3, Output: 100,101...999 //note the 3 digit numbers are returned. The range would be 100 to 999. How can i achieve this. Is there any formula to get the range.
