Answer:The answer is 19.

Step-by-step explanation:We first need to calculate the powers, roots, products and divisions in the order they appear from left to right. For this expression we have:

5² – sqrt(8 + 56:2)

25 – sqrt(8 + 56:2)

25 – sqrt(8 + 28)

25 – sqrt(36)

25 – 6

Now we can calculate the sums and subtractions in the order they appear, from left to right:

25 – 6

19

The answer is 19
