To calculate - 3 * 10 ^ - 3 - 6.7 * 10, we can multiply -3 by 10 raised to the power of -3 and subtract it from 6.7 * 10.
-3 * 10 ^ -3 = -0.003
6.7 * 10 = 67.0
Now we can subtract -0.003 from 67.0:
67.0 - 0.003 = 66.997
Finally, we can express the answer in scientific notation by moving the decimal point two places to the left, resulting in:
6.70 * 10 ^ 1
Calculate - 3 * 10 ^ - 3 - 6.7 * 10 Express the answer in scientific notation rounding to 2 decimal places.
