Rekenmachine-invoer Uitgelegd
Base (x): The number being multiplied by itself, can be any real number
Exponent (y): The power to which the base is raised, determines how many times to multiply
Positive exponents: Multiply base by itself y times (e.g., 2^3 = 2×2×2)
Negative exponents: Reciprocal of positive exponent (e.g., 2^-3 = 1/(2^3))
Fractional exponents: Represent roots (e.g., x^(1/2) is square root of x)
Hoe De Berekening Werkt
The calculator computes x^y using the exponential function. For positive integer exponents, it represents repeated multiplication: x^y = x × x × x... (y times). For negative exponents, x^-y = 1/(x^y). For fractional exponents, x^(m/n) = ⁿ√(x^m), the nth root of x to the power m. Special cases include: x^0 = 1 for any x ≠ 0, x^1 = x, and 0^0 is considered undefined. The result is displayed in scientific notation (a × 10^b) when the value is very large (>1e10) or very small (<1e-4).
Voorbeeldscenario's
Example 1: 2^3 = 8. Base is 2, exponent is 3. Result: 2 × 2 × 2 = 8
Example 2: 10^-2 = 0.01. Negative exponent means reciprocal: 1/(10^2) = 1/100 = 0.01
Example 3: 16^0.5 = 4. Fractional exponent 0.5 = 1/2, so this is the square root of 16
Example 4: 5^4 = 625. Calculate 5 × 5 × 5 × 5 = 625
Example 5: 2^10 = 1024. Shows larger power calculation, useful in computer science

Frequently Asked Questions
What is an exponent?
An exponent indicates how many times to multiply a base number by itself. In x^y, y is the exponent. For example, 2^3 means 2 × 2 × 2 = 8.
How do negative exponents work?
A negative exponent means the reciprocal of the positive exponent. x^-y = 1/(x^y). For example, 2^-3 = 1/(2^3) = 1/8 = 0.125.
What are fractional exponents?
Fractional exponents represent roots. x^(1/n) is the nth root of x. For example, 16^(1/2) is the square root of 16, which equals 4. x^(m/n) = ⁿ√(x^m).
What is 0^0?
0^0 is mathematically undefined or considered indeterminate. Different contexts may treat it differently, but this calculator flags it as a special case requiring consideration.
Can I use negative bases?
Yes for integer exponents. For fractional exponents with negative bases, the result may be complex (imaginary), which this calculator will indicate as it only handles real numbers.
Why use scientific notation?
Scientific notation (a × 10^b) makes very large or very small numbers easier to read and understand. For example, 2^50 = 1.126 × 10^15 is clearer than 1,125,899,906,842,624.
