Answer 2

To calculate the expression, you need to follow the order of operations (PEMDAS/BODMAS):

1. Perform multiplication and division from left to right.
2. Then, perform addition and subtraction from left to right.

Let's calculate step by step:

1. 5 * 10^-2 = 5 * 0.01 = 0.05
2. 7 * 10^-3 = 7 * 0.001 = 0.007
3. 8 * 10^-4 = 8 * 0.0001 = 0.0008

Now, we add the results together:

0.05 + 0.007 + 0.0008 = 0.0578

So, the final answer is 0.0578.
