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 ·... ·a \(=\) \(a^n\), where \(a\) is the base and \(n\) is the exponent.
Example:
“\(3\) to the power \(4\)” may be written as 34.
 
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 34 \(= 81\).
