Practice makes perfect
We need to remember the order of operations to evaluate the given numeric expression. The acronym PEMDAS can help with that!

Let's now consider our expression. sqrt(54/6) + 2/3 First, we need to calculate the square root. We will start by simplifying the quotient inside the radicand. sqrt(54/6)+2/3 divide âź¶ sqrt(9)+2/3 Next, we can calculate the square root. Because we know that 3^2=9, we also know that sqrt(9)=3. \begin{gathered} \sqrt{\textcolor{olive}9}+\dfrac{2}{3}\quad \stackrel{\text{calculate root}}{\longrightarrow} \quad \textcolor{deepskyblue}3+\dfrac{2}{3} \end{gathered} Now we can finish evaluating our expression. The fraction cannot be divided into an integer. Therefore, we only need to add the terms.
