    What is Fourth Roots?

    The fourth root of a number is a mathematical operation that finds a number which, when raised to the fourth power, equals the given number. In other words, it’s the inverse operation of taking a number to the fourth power. The fourth root is denoted by the radical symbol with a small “4” as an index.

    All Formulae Related to Fourth Roots

    1. Fourth Root Definition:
      • The fourth root of a number “a” is represented as ∜a.
      • ∜a is the number x such that x^4 = a.
    2. Fourth Root of a Product:
      • ∜(ab) = ∜a * ∜b
      • The fourth root of the product of two numbers is equal to the product of their fourth roots.
    3. Fourth Root of a Quotient:
      • ∜(a/b) = ∜a / ∜b
      • The fourth root of the quotient of two numbers is equal to the quotient of their fourth roots.
    4. Fourth Root of a Power:
      • (∜a)^n = ∜(a^n)
      • Raising the fourth root of a number to a power is equivalent to taking the fourth root of that number raised to the same power.
    5. Reciprocal of Fourth Root:
      • 1/∜a = ∜(1/a)
      • The reciprocal of the fourth root of a number is equal to the fourth root of the reciprocal of that number.
    6. Fourth Root of a Negative Number:
      • The fourth root of a negative number is not a real number but can be expressed as a complex number.
    7. Properties of Fourth Roots:
      • Fourth roots are a type of radical and follow similar mathematical properties as square roots and cube roots, including the distributive property and rules for combining like terms.
    8. Calculating Fourth Roots:
      • Calculating fourth roots can be done using calculators, software, or numerical methods, especially for non-perfect fourth roots (numbers that are not exact fourth powers).
