subtract 8.03 ✕ 10-8 2.56 ✕ 10-2

Answer 1

To subtract the two numbers with exponents, we need to have the same exponent for both. So, we can convert 2.56 × 10^-2 to the same exponent as 8.03 × 10^-8.

To do this, we can multiply 2.56 by 10^6 and divide 10^-2 by 10^6, which will give us 2.56 × 10^-8.

Now, we can perform the subtraction:

8.03 × 10^-8 - 2.56 × 10^-8 = (8.03 - 2.56) × 10^-8 = 5.47 × 10^-8
