Final answer:
To subtract (8.8 x 10/7) - (6 x 10/7), subtract the coefficients directly and keep the exponent the same. The result is 2.8 x 10/7, which is already in scientific notation.
Step-by-step explanation:
To subtract the given numbers in scientific notation, you need to ensure they have the same exponent. In this case, they both have the exponent ⅗ (which stands for 10 divided by 7, or 10/7). Hence, you can directly subtract the coefficients (the numbers in front of the exponent).
Here is the calculation:
(8.8 × 10⅗) - (6 × 10⅗)
The subtraction of the coefficients 8.8 and 6 gives:
8.8 - 6 = 2.8
The exponent remains the same since we didn't change the order of magnitude. Therefore, the result in proper scientific notation is:
2.8 × 10⅗
