Example: 2³ = 2 × 2 × 2 = 8
Negative exponent: a⁻ⁿ = 1/aⁿ
Example: 2⁻³ = 1/2³ = 1/8 = 0.125
Root extraction
Formula: ⁿ√a = a^(1/n)
Example: ³√8 = 8^(1/3) = 2
Square root: √a = a^(1/2)
Cube root: ³√a = a^(1/3)
Exponential functions
Formula: e^x = exp(x)
Example: e² ≈ 7.389
Properties: e⁰ = 1, e¹ = e ≈ 2.718
Logarithms
Formula: ln(x) = logₑ(x)
Example: ln(8) ≈ 2.079
Properties: ln(1) = 0, ln(e) = 1
Scientific notation

Frequently asked questions
What is the difference between exponentiation and root extraction?
Exponentiation is calculating a number raised to a given exponent (a^b), while root extraction is the inverse operation of exponentiation (ⁿ√a = a^(1/n)).
How do I calculate a power with a negative exponent?
In the case of a negative exponent, the power is the reciprocal of the power with a positive exponent: a⁻ⁿ = 1/aⁿ. For example: 2⁻³ = 1/2³ = 1/8 = 0.125.
What is the number e?
e (Euler's number) is a mathematical constant with a value of approximately 2.718. It is the base of the natural logarithm and appears in many mathematical formulas.
How accurate is the calculator?
The calculator performs calculations with high precision, up to 10 decimal places. The precision can be adjusted on the interface.
