Radical Multiplication Rule:
From: | To: |
The multiplication of radicals follows the mathematical rule that the product of two square roots is equal to the square root of the product of their radicands. This is a fundamental property in algebra and simplifies many mathematical operations.
The calculator uses the radical multiplication rule:
Where:
Explanation: The calculator first multiplies the radicands (a and b), then takes the square root of the product, giving you both the simplified radical form and its decimal approximation.
Details: Understanding radical multiplication is essential for simplifying expressions, solving equations, and working with quadratic forms in algebra and higher mathematics.
Tips: Enter any non-negative numbers for a and b. The calculator will show the simplified radical form and its decimal value. Both inputs must be valid (≥ 0).
Q1: Can I multiply radicals with different indices?
A: This calculator is for square roots (index 2) only. Different indices require more complex calculations.
Q2: What if one radicand is negative?
A: The calculator only accepts non-negative radicands as square roots of negative numbers involve complex numbers.
Q3: Does this work for variables too?
A: The principle applies to variables (e.g., √x * √y = √(xy)), but this calculator only handles numerical inputs.
Q4: Can I simplify before multiplying?
A: Yes, sometimes simplifying individual radicals first can make calculations easier, but the final result will be the same.
Q5: How precise are the results?
A: Results are accurate to 4 decimal places, but exact form is shown when possible.
