Answer

So, the result of the expression is \(\boxed{128}\).

Steps

Step 1 ：Calculate \(4^2\), which is 16.

Step 2 ：Subtract 16 from 18, which gives 2.

Step 3 ：Add 2 to the result, which gives 4.

Step 4 ：Square 4, which gives 16. So, the numerator is 16.

Step 5 ：Divide 1 by 4, which gives 0.25.

Step 6 ：Multiply 0.25 by 1/2, which gives 0.125. So, the denominator is 0.125.

Step 7 ：Finally, divide the numerator by the denominator. \(16 ÷ 0.125 = 128\).

Step 8 ：So, the result of the expression is \(\boxed{128}\).
