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.
