8.03x10^-8-2.56x10^-2

Answer 1

To subtract these numbers in scientific notation, we need to make sure the exponents are the same.

8.03x10^-8 - 2.56x10^-2

The exponent of the first number is -8, and the exponent of the second number is -2. To make them the same, we can convert the second number to scientific notation with an exponent of -8:

2.56x10^-2 = 0.256x10^-1 = 2.56x10^-2

Now that the exponents are the same, we can subtract the numbers:

8.03x10^-8 - 2.56x10^-8 = 5.47x10^-8
