Definition of Exponentiation

Description

This equation shows the definition of the exponentiation operation, given a base (\( \htmlClass{sdt-0000000003}{x} \)) and an exponent \((\htmlClass{sdt-0000000017}{y})\). It can be thought of, in plain english, as multiplying the base, in this case \( \htmlClass{sdt-0000000003}{x} \), by itself the exponent (in this case \( \htmlClass{sdt-0000000017}{y} \)) amount of times. Simpler: \( \htmlClass{sdt-0000000003}{x} \) is multiplied by itself \( \htmlClass{sdt-0000000017}{y} \) times. In product notation, it is...

\[\htmlClass{sdt-0000000003}{x}^{\htmlClass{sdt-0000000017}{y}} = \htmlClass{sdt-0000000097}{\prod}_{\htmlClass{sdt-0000000018}{i} = 1}^{\htmlClass{sdt-0000000017}{y}} \htmlClass{sdt-0000000003}{x}\]

Symbols Used:

This is a symbol for any generic variable. It can hold any value, whether that be an integer or a real number, or a complex number, or a matrix etc.

\( y \)

This is a secondary symbol for any generic variable. It can hold any value, whether that be an integer or a real number, or a complex number, or a matrix etc.

\( i \)

This is the symbol for an iterator, a variable that changes value to refer to a sequence of elements.

\( \prod \)

This is the product symbol in mathematics, denoted as the uppercase Greek letter Pi. It is used to indicate the product of a sequence of factors.

Derivation

This is by definition

Example

Calculate the value of \(3^5\)

This is going to be...

\[ 3 \cdot 3 \cdot 3 \cdot 3 \cdot 3\]

which evaluates to the value \(243\).
