# Subtracting Exponents
To understand subtraction of exponents, let's start from a simple example.
Example. Suppose, we want to find (2^7)/(2^4).
We already learned about positive integer exponets, so we can write, that 2^7=2*2*2*2*2*2*2 and 2^4=2*2*2*2.
So, (2^7)/(2^4)=(2*2*2*color(red)(2*2*2*2))/(color(red)(2*2*2... |

POWER SET OF A SET
The set of all subsets of A is said to be the power set of the set A.
The power set of A is denoted by P(A).
Example 1 :
Let A = {1, 2, 3}. Find the power set of A.
Solution :
We know that the power set is the set of all subsets.
Here, the given set A contains 3 elements.

We denote the product of the first $20$ natural numbers by $20!$ and call this $20$ factorial.
1. What is the highest power of $5$ which is a divisor of $20$ factorial?
We have $20! = 20 \times 19 \times 18 \times \dotsm \times 3 \times 2 \times 1$.
