What is \( 3 \times \sqrt{18} \)?
Answer (3)
3 ⋅ 18 = 3 ⋅ 9 ⋅ 2 = 3 ⋅ 9 ⋅ 2 = 3 ⋅ 3 ⋅ 2 = 9 2
The square root of 18 = 4.24264068712. Rounding it would just be 4.2. Then 3 times 4.2 is 12.6
The expression 3 × 18 simplifies to 9 2 . This is done by breaking down 18 into simpler square roots. The final result is a clear multiplication of constants and the square root term.
