2. What is an exponent?

The base a raised to the power of n is equal to the multiplication of a, n times:

$a$ is the base and $n$ is the exponent.

 

For example, “3 to the power 4” may be written as $3^4$. Here, the base number is $3,$ and the exponent is $4$. It means that $3$ is being multiplied by itself $4$ times: $3$ x $3$ x $3$ x $3$.

Where,

$3$ x $3$ x $3$ x $3$ $=$ $81$ or $3^4$ = $81.$
