Understanding Modular Exponentiation
Modular exponentiation is calculating $$b^e \mod m$$, where $$b$$ is the base, $$e$$ is the exponent, and $$m$$ is the modulus. It's a core operation in cryptography and number theory, used in algorithms like RSA. It efficiently finds the remainder of a large exponentiation without computing the full power.
Formula:
$$Result = (Base ^ {Exponent}) \mod Modulus$$
Example:
Calculate $$3^4 \mod 5$$.
- $$3^4 = 81$$
- $$81 \mod 5 = 1$$
- Therefore, $$3^4 \mod 5 = 1$$.
This calculator uses an efficient algorithm suitable for large numbers.

Modular exponentiation is like finding the remainder after a big power calculation. Imagine you want to calculate (53) mod 7. First, 53 is 125. Then, divide 125 by 7; the remainder is 6. So, (53) mod 7 = 6. This tool helps you do this quickly for any base, exponent, and modulus, which is useful in computer security and math problems.
