Subtract 4.66 × 10^-5
- 7.34 × 10^-7 (1 point)
4.66 × 10^-5 - 7.34 × 10^-7 = 4.59 × 10^-5 (rounded to two decimal places)
2.68x10^2
4.5866x10^-5
-3.5866x10^-5
-2.68x10^2
2.68 × 10^2 + 4.5866 × 10^-5 - 3.5866 × 10^-5 - 2.68 × 10^2 = (2.68 - 0.000011) × 10^2 = 2.679989 × 10^2 (rounded to six decimal places)
no those are the answer choices
Apologies for misunderstanding. Based on the given answer choices, the correct calculation is:
2.68 × 10^2 - (- 2.68 × 10^2) = (2.68 + 2.68) × 10^2 = 5.36 × 10^2 (rounded to two decimal places)
not even an option
Apologies for the confusion. If none of the given options are correct, it seems there may have been an error in the problem or the answer choices provided. Please double-check the options or provide additional information so that I can assist you further.

-4.5866x10^-5
-2.68x10^2
To find the result of subtracting 4.5866x10^-5 from 2.68x10^2, you would subtract the coefficients and keep the same exponent:
2.68x10^2 - 4.5866x10^-5 = 2.68x10^2 - 0.000045866 = 2.679954x10^2 (rounded to six decimal places).
Therefore, the correct answer would be -2.68x10^2.
To subtract two numbers in scientific notation, we need to make sure they have the same exponent.
Given:
First number: 4.66 × 10^-5
Second number: 7.34 × 10^-7
Step 1: Rearrange the second number to match the exponent of the first number.
7.34 × 10^-7 can be written as 0.0734 × 10^-5 by moving the decimal point two places to the right.
Now, we can subtract the numbers:
4.66 × 10^-5 - 0.0734 × 10^-5
Step 2: Perform the subtraction of the coefficients (the numbers in front of the exponents):
4.66 - 0.0734 = 4.5866
Step 3: Keep the common exponent, which is 10^-5 in this case.
Put it all together:
4.5866 × 10^-5
So, the answer to the subtraction is 4.5866 × 10^-5.
