Again, just multiply the numbers, and then multiply the powers of 10.

%282.5%2A%2810%5E-12%29%29%2A%282%2A%2810%5E6%29%29

%282.5%2A2%29%2A%2810%5E-12%29%2A%2810%5E6%29%29

%285%29%2A%2810%5E-6%29 multiply the regular numbers, then add the exponents of the 10's together

5%2A%2810%5E-6%29 should be your final answer

When you get to the final answer, it should always be

some number (using only the ones digit) x 10 to another number power

Here are some CORRECT examples of scientific notation:

3%2A10%5E5

2.94865%2A10%5E8

5.9%2A10%5E-4

Here are some INCORRECT examples of scientific notation:

256.3%2A10%5E5

.00005%2A10%5E-3

I hope this helps!
