Remember the order of operations.

8

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

Let's now consider our expression.

sqrt(6.76) + 5.4 We first need to calculate the square root. Because we know that (2.6)^2=6.76, we know that sqrt(6.76)=2.6. sqrt(6.76)+5.4 calculate root ⟶ 2.6+5.4 Now we can finish evaluating our expression by adding the remaining terms. 2.6+5.4 ⇔ 8
