    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
