Calculation Results

Original Expression

sqrt(72) + cbrt(64) - root(4,81)

Simplified Form

6√2 + 4 - 3

Decimal Approximation

9.4853

Step-by-Step Solution

Step 1: Simplify sqrt(72)
72 = 36 × 2 = 6² × 2
sqrt(72) = sqrt(6² × 2) = 6√2
Step 2: Simplify cbrt(64)
64 = 4³
cbrt(64) = cbrt(4³) = 4
Step 3: Simplify root(4,81)
81 = 3⁴
root(4,81) = root(4,3⁴) = 3
Step 4: Combine results
6√2 + 4 - 3 = 6√2 + 1

Additional Information

• Expression contains 3 radical terms
• All radicals can be simplified
• Final form: 6√2 + 1 ≈ 9.4853
• Domain: All real numbers
