When working with the expression 3 x square root of 3, there are several common mistakes that students and professionals should avoid:

1. Incorrect Simplification:
   • A common error is attempting to simplify \(3 \times \sqrt{3}\) incorrectly by mistakenly applying algebraic rules that do not apply to square roots.
   • For example, thinking that \(3 \times \sqrt{3} = \sqrt{3 \times 3}\) is incorrect. The correct simplification is to keep the multiplication separate: \(3 \times \sqrt{3}\).
2. Misunderstanding the Square Root:
   • Another mistake is misinterpreting the value of \(\sqrt{3}\). It is important to recognize that \(\sqrt{3}\) is an irrational number approximately equal to 1.732, not a whole number.
3. Incorrect Use of Decimal Approximations:
   • When using decimal approximations, ensure accuracy by using enough decimal places. For example, \(\sqrt{3} \approx 1.732\) should be used rather than truncating to a shorter value, which can lead to significant errors in calculations.
4. Omitting Units:
   • In practical applications, forgetting to include units (e.g., meters, Newtons) can lead to confusion and incorrect interpretations of results. Always specify the units when expressing the result of \(3 \times \sqrt{3}\).
5. Neglecting Exact Forms:
