Exponentiation is a mathematical operation involving the raising of a base number to the power of an exponent. It is denoted as
𝑎
𝑏
a
b
, where
𝑎
a is the base and
𝑏
b is the exponent. Exponentiation is fundamental in algebra, calculus, and computational mathematics, and it plays a crucial role in fields like cryptography, physics, and engineering.
