Calculation History

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

• 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.

• Multiply by appropriate factors to make the radicands the same, if possible.

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

• 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.

• √(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)
