and

\mathrm{n}

elements respectively. Then, the total number of mappings from

A

\mathrm{B}

is :

View answer and explanation

Correct option: D

\mathrm{n}^{\mathrm{m}}

Option D (

n^m

) is correct because each of the m elements in set A can be mapped to any of the n elements in set B, resulting in

n^m

possible mappings.
