    What are Radicals and Roots?

    Radicals and roots are mathematical concepts related to the extraction of a specific root of a number. They are fundamental in algebra and arithmetic and are used to express numbers in a different form.

    All Formulae Related to Radicals and Roots

    Square Root Formula:

    • The square root (√) of a number “a” is denoted as sqrt(a).
    • The square root of a number “a” can also be expressed as a^(1/2).

    Cube Root Formula:

    • The cube root (3√) of a number “a” is denoted as cbrt(a).
    • The cube root of a number “a” can also be expressed as a^(1/3).

    nth Root Formula:

    • The nth root (n√) of a number “a” is denoted as n√(a).
    • The nth root of a number “a” can be expressed as a^(1/n).

    Properties of Radicals and Roots:

    1. Product of Radicals: sqrt(ab) = sqrt(a) * sqrt(b)
    2. Quotient of Radicals: sqrt(a) / sqrt(b) = sqrt(a/b)
    3. Power of a Radical: (sqrt(a))^n = sqrt(a^n)
    4. Radical of a Power: n√(a^m) = a^(m/n)
    5. Radical of a Radical: n√(m√(a)) = (n*m)√(a)
    6. Conjugate Radical: sqrt(a) * sqrt(a) = a

    Radical Simplification:

    • To simplify a radical expression, factor the radicand and express it in terms of perfect squares, cubes, etc.
    • For example, sqrt(18) = sqrt(9) * sqrt(2) = 3√2.
