🔹 What is Multiplying Square Roots?

Multiplying square roots follows the fundamental rule of radicals:

√a × √b = √(a × b)

Example:

• √2 × √8 = √(2 × 8) = √16 = 4
• √3 × √12 = √36 = 6

Key points:

• Multiplying square roots can simplify expressions efficiently.
• The product of two square roots is always a square root of the product of the numbers.
• This rule works for all positive real numbers and can be extended to decimals and fractions.
