0,0024^2/2×10^-4

To solve this expression, we follow the order of operations (also known as PEMDAS).

First, we calculate the square of 0.0024: 0.0024^2 = 0.00000288

Next, we divide the result by 2x10^-4: 0.00000288 / (2x10^-4)

To divide by a number in scientific notation, we can rewrite it as the reciprocal. So, we have: 0.00000288 / (2x10^-4) = 0.00000288 x (1/(2x10^-4))

Simplifying further, we have: 0.00000288 x (1/(2x10^-4)) = 0.00000288 x (1/(0.0002))

Now, divide 1 by 0.0002: 1 / 0.0002 = 5000

Finally, multiply 0.00000288 by 5000: 0.00000288 x 5000 = 0.0144

Therefore, 0.0024^2/2×10^-4 is equal to 0.0144.
