    What is Radical Expression?

    A Radical Expression, simply called a “radical,” is a mathematical expression that includes a radical symbol (√) indicating the extraction of a root of a number or expression. The most common type of radical is the square root (√), which signifies the extraction of the square root of a number. However, other radicals, such as cube roots (∛), fourth roots (∜), and so on, can also be used.

    All Formulae Related to Radical Expressions

    Simplifying Radicals:

    • Find the largest perfect square divisor of the radicand (number under the radical symbol).
    • Extract the perfect square and its corresponding square root outside the radical.
    • Simplify the remaining radicand, if possible.

    Example: Simplify √50.

    • Largest perfect square divisor of 50 is 25 (5^2).
    • √50 = √(25 * 2) = 5√2.

    2. Rationalizing the Denominator (for expressions with radicals in the denominator):

    • Multiply both numerator and denominator by the conjugate of the denominator (expression obtained by flipping the sign of the radicand and multiplying it by its simplified form).

    Example: Rationalize 1/(√2 + 1).

    • Conjugate of (√2 + 1) is (√2 – 1).
    • (1/(√2 + 1)) * ((√2 – 1)/(√2 – 1)) = (√2 – 1) / (2 – 1^2) = √2 – 1.

    3. Adding and Subtracting Radicals:

    • Radicals must be like (have the same radicand) to be added or subtracted directly.
    • Multiply by appropriate factors to make the radicands the same, if possible.
    • Add or subtract the coefficients (numbers multiplying the radicals).

    Example: Add √16 and √8.

    • 8 can be expressed as 4 * 2, where 4 is a perfect square.
    • √16 + √8 = √16 + √(4 * 2) = 4 + 2√2.

    4. Multiplying and Dividing Radicals:

    • Multiply radicands and coefficients separately.
    • Simplify resulting radicand, if possible.
    • For dividing, rationalize the denominator if necessary.

    Example: Multiply √2 and √6.

    • √2 * √6 = √(2 * 6) = √12 = 2√3.

    5. Properties of Radicals:

    • √(ab) = √a * √b (a and b are positive numbers)
    • √(a^n) = a^(n/2) (n is any even positive integer)
    • a^(1/n) = nth root of a (a is any positive number, n is any positive integer)
