38, we have to simplify the brackets first by distributing the ^2 among them, by following the formula X^2 - 2XY + Y^2, which in this case will be 10^2 - 2.10.8 + 8^2 = 100-160+64 = 4 , so the new equation is 4 + 36 / 4 . 3 + 7,,, by following PEMDAS (rule of order of operations) multiplication and division processes are done first from left to right, so 36/4 = 9 ,, 9 . 3= 27 , so the 27 replaces the (36/4 . 3) part and the resulting equation is 4+27 +7,, finally subtraction and addition are also from left to right, so the answer is 38, you can check your answer from the calculator
