Modular exponentiation calculatorCompute aᵇ mod n efficiently with fast (square-and-multiply) exponentiation and big integers, so even astronomically large powers reduce in a fraction of a second. It normalises a negative or oversized base into the range 0…n−1 first, and supports negative exponents when the base is invertible modulo n. This is the core operation behind RSA, Diffie–Hellman and primality testing.Absolute Value Equation SolverSolve absolute-value equations like |x+3| = 5, 3|x+2| = 12 or |x+1| = |x−3| with step-by-step case analysis and exact solutions.Absolute Value Inequality SolverSolve absolute-value inequalities such as |x+3| < 5 or |x−2| > 3 and get the solution as an interval, with AND/OR reasoning explained step by step.Algebraic Expression SimplifierCombines like terms, expands or factors, with implicit multiplication understood (2x is 2·x). When a cancellation removes a factor, the excluded value is stated — (x²−4)/(x−2) is x+2 only for x ≠ 2, and that restriction is part of the answer.Beta Function CalculatorCompute the Euler Beta function B(x, y) = Γ(x)·Γ(y) / Γ(x+y) via a stable log-gamma.Boolean Algebra SimplifierReduces a boolean expression to a minimal sum of products, accepting every common notation — AB, A·B, A&B for AND, A+B or A|B for OR, ~A, !A or A' for NOT, plus XOR, NAND and NOR. Shows the prime implicants, not just the final answer.Complementary Error Function CalculatorCompute erfc(x) = 1 − erf(x) to high precision, accurate even far in the tail.Completing the Square CalculatorRewrite ax² + bx + c into vertex form a(x − h)² + k, with the vertex, the completed-square steps and the real or complex roots.

Enter Base, Exponent and the Exponent calculator works out Result straight away. For instance, with Base = 2 and Exponent = 10 it returns Result = 1,024.

How to use it

  1. Enter your values: Base, Exponent.
  2. Read the result instantly: Result.

Frequently asked questions

How does the Exponent calculator work?

It takes Base and Exponent and derives Result from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

2 values: Base and Exponent. Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Base = 2 and Exponent = 10, the calculator returns Result = 1,024. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Base = 4 and Exponent = 20 instead, Result goes from 1,024 to 1,099,511,628,000 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Base = 1 and Exponent = 5, Result comes out at 1. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Getting through a problem set: solving for the unknown, factoring an expression, and — more usefully — seeing the steps that got there.

What is the most common mistake?

Losing a solution when both sides are squared or divided by an expression. Squaring can add roots that do not satisfy the original equation, and dividing can remove one — check every answer back in the original.

What is the difference between the Exponent calculator and the Modular exponentiation calculator?

This one returns Result; the Modular exponentiation calculator returns aᵇ mod n and Base reduced (a mod n). That is the whole difference — open the one whose figure you need.

Where do the figures come from, and how current are they?

The algebra is symbolic where the expression allows it and numeric otherwise, and the tool says which it used. Exact results are given as fractions or radicals rather than rounded decimals.
