### Theory:

An exponent is a small number written above and to the right of the base number, tells how many times the base number is being multiplied.

The base $$a$$ raised to the power of $$n$$ is equal to the multiplication of $$a$$, $$n$$ times:
$a·a·a·\mathrm{...}·a$ $$=$$ $$a^n$$, where $$a$$ is the base and $$n$$ is the exponent.
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: $$3 \times 3 \times 3 \times 3$$.

Where, $$3 \times 3 \times 3 \times 3$$ $$=$$ $$81$$ or ${3}^{4}$ $$= 81$$.
$\begin{array}{l}{3}^{1}=3\\ {3}^{2}=3·3=9\\ {3}^{3}=3·3·3=27\\ {3}^{4}=3·3·3·3=81\\ {3}^{5}=3·3·3·3·3=243\end{array}$
