0,0024^2/2×10^-4

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. First, evaluate the exponent:

0,0024^2 = 0,0024 * 0,0024 = 0,00000576

2. Next, divide by 2:

0,00000576 / 2 = 0.00000288

3. Finally, multiply by 10^-4 (which is equivalent to moving the decimal point 4 places to the left):

0.00000288 * 10^-4 = 0.0000000000288

So, 0,0024^2/2×10^-4 = 0.0000000000288
