Mathematical formulas and explanations

Square root

Formula: √a = a^(1/2)

Example: √16 = 16^(1/2) = 4

Properties: √a² = |a|, √(a×b) = √a × √b

Negative numbers: √(-a) = i√a (where i is the imaginary unit)

Cube root

Formula: ³√a = a^(1/3)

Example: ³√8 = 8^(1/3) = 2

Properties: ³√a³ = a, ³√(a×b) = ³√a × ³√b

Negative numbers: ³√(-a) = -³√a

Nth root

Formula: ⁿ√a = a^(1/n)

Example: ⁴√16 = 16^(1/4) = 2

Properties: ⁿ√aⁿ = |a| (even n), ⁿ√aⁿ = a (odd n)

Exponentiation: (ⁿ√a)ᵐ = ⁿ√(aᵐ)

Decimal root

Formula: a^(1/n), where n is a decimal number

Example: 16^(1/2.5) ≈ 2.297

Application: Complex mathematical calculations

Complex root

Formula: ⁿ√(a+bi) = r^(1/n) × e^(iθ/n)

Example: √(-4) = 2i

Application: Determining roots of complex numbers

Frequently asked questions

What is the difference between a square root and a cube root?

The square root is the second root of a number (√a = a^(1/2)), while the cube root is the third root of a number (³√a = a^(1/3)).

How do I calculate the root of negative numbers?

The square root of negative numbers is a complex number: √(-a) = i√a. For cube roots: ³√(-a) = -³√a. An even-degree root of a negative number yields a complex result.

What is the relationship between root extraction and exponentiation?

Root extraction is the inverse operation of exponentiation: ⁿ√a = a^(1/n). This means that root extraction can also be performed using exponentiation.

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.
