A mistake was made in simplifying the expression given below.Simplify:...
To simplify the expression, we need to follow the order of operations (PEMDAS): parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Starting with the given expression:
5 + 2(6 - 4)^2

First, we simplify the expression within the parentheses:
5 + 2(2)^2

Next, we simplify the exponent:
5 + 2(4)

Then, we perform the multiplication:
5 + 8

Finally, we add:
13

Therefore, the correct simplified expression is 13.
