Prove by permutations or otherwise $\displaystyle \frac{\left(n!\right)!}{\left(n!\right)^{(n-1)!}}$, where $n\in \mathbb{N}$
An integer quantity is a mathematical concept that refers to a whole number, either positive, negative, or zero. It is a discrete value that does not include fractions or decimals.
An integer quantity is a subset of the rational numbers, which includes all integers as well as fractions and decimals. Unlike a rational number, an integer quantity does not include any numbers after the decimal point.
Yes, an integer quantity can be negative. Negative integers are represented with a minus sign in front of the number, such as -5 or -100.
Integer quantities can be used to represent a variety of real-world situations, such as the number of people in a room, the temperature outside, or the amount of money in a bank account. They can also be used in counting, measuring, and indexing.
Integer quantities are used extensively in scientific experiments and calculations. They are often used to represent discrete values, such as the number of particles in a sample, the number of trials in an experiment, or the time intervals in a measurement. They are also used in scientific notation to express very large or very small numbers in a compact form.
