To simplify the expression 5(14 - 2)²/2, we can follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

First, let's simplify what is inside the parentheses:

14 - 2 = 12.

Now, substitute the value back into the expression:

5(12)²/2.

Next, we solve the exponent:

12² = 144.

Now, substitute the value back into the expression:

5(144)/2.

Next, perform the multiplication:

5 * 144 = 720.

Now, substitute the value back into the expression:

720/2.

Finally, perform the division:

720/2 = 360.

Therefore, the simplified form of the expression 5(14 - 2)²/2 is 360.
