8.03x10^-8 minus 2.56x10^-2 scientific notation

Answer 1

To subtract numbers in scientific notation, you need to have the same power of 10.

First, convert 8.03x10^-8 to the same power of 10 as 2.56x10^-2:

8.03x10^-8 = 8.03x10^-8 x 10^10/10^10 = 8.03x10^2 x 10^-10

Now subtract the numbers:

8.03x10^2 x 10^-10 - 2.56x10^-2

= (8.03 x 10^2) x (10^-10) - (2.56 x 10^-2)

= 8.03 x 10^2 - 2.56 x 10^-2

= 803 - 0.0256

= 802.9744

Therefore, 8.03x10^-8 - 2.56x10^-2 in scientific notation is 8.029744x10^2.
