8.03 ✕ 10v-8 - 2.56 ✕ 10v-2 show your work

Answer 1

To solve this, we can simplify each term separately.

8.03 × 10^(-8) can be written as 0.0000000803 (moving the decimal point 8 places to the left).

2.56 × 10^(-2) can be written as 0.0256 (moving the decimal point 2 places to the left).

Subtracting them, we get:

0.0000000803 - 0.0256

Now, we can align the decimal points and calculate:

0.0000000803
- 0.0256
_______________
0.0000000547

Therefore, 8.03 × 10^(-8) - 2.56 × 10^(-2) = 0.0000000547.
