FK2=36+64-2*6*8*2/2

Let's solve the expression step-by-step, following the order of operations (PEMDAS/BODMAS):

1. Calculate the multiplication and division from left to right: \[ 2 * 6 * 8 * 2 = 192 \] \[ 192 / 2 = 96 \]

2. Now substitute that back into the expression: \[ FK2 = 36 + 64 - 96 \]

3. Next, perform the addition and subtraction from left to right: \[ 36 + 64 = 100 \] \[ 100 - 96 = 4 \]

So, \( FK2 = 4 \).
