The answer depends on the sequence of operations, which is not specified in the question. E.g. 8 plus (4 squared) is not the same statement as (8 plus 4) squared.

When working with parentheses in mathematics, you work what is inside the parenthesis first. In this case are were no parentheses.

Strictly following the question, the statement is {[8 + (4)2 ] /8} x 4 = (8+16)x2 = 48.
If the (8 plus 4) is squared, the answer is 72.
