Exponents and powers are basic concepts in
mathematics that simplify the expression of large
numbers and complex calculations. 
I N T R O D U C T I O N
I N T R O D U C T I O N
An exponent indicates how many times a number,
called the base, is multiplied by itself.

The exponent of a number tells us how
many times a base number is multiplied
by itself.
This tells us that a is multiplied by itself
two times.
