Example: Using the Radicals Calculator
Example 1: Simplifying a Square Root
- Expression: √72
Steps:
- Factor 72 into prime factors: 72 = 2 × 2 × 2 × 3 × 3
- Pair factors under the square root: (2×2) and (3×3)
- Simplify: √72 = √(2² × 3² × 2) = 2 × 3 √2 = 6√2
Result:
- Simplified form: 6√2
Example 2: Simplifying a Cube Root
- Expression: ∛54
Steps:
- Factor 54: 54 = 2 × 3 × 3 × 3
- Group factors for cube root: ∛(3³ × 2)
- Simplify: ∛54 = 3∛2
Result:
- Simplified form: 3∛2
Example 3: Radical with Variables
- Expression: √(50x²)
Steps:
- Factor 50x²: 50x² = 25 × 2 × x²
- Simplify: √(25 × 2 × x²) = √25 × √x² × √2 = 5x√2
Result:
- Simplified form: 5x√2
Example 4: Solving a Radical Equation
- Equation: √(x + 5) = 3
Steps:
- Square both sides: x + 5 = 9
- Solve for x: x = 4
- Check solution: Substitute x = 4 into the original equation → √(4 + 5) = √9 = 3 ✅
Result:
- Solution: x = 4
