Subtract 4.66 * 10 ^ - 5 - 7.34 * 10 ^ - 7 (1 point)
2.68 * 10 ^ 2
4.5866 * 10 ^ - 5
- 2.68 * 10 ^ 2
- 4.5866 * 10 ^ - 5
-4.58656 * 10^-5
To subtract 4.66 * 10^-5 from 7.34 * 10^-7, you follow these steps:
Step 1: Rewrite the numbers in scientific notation, if necessary.
7.34 * 10^-7 becomes 0.00000734
4.66 * 10^-5 remains as is.
Step 2: Subtract the numbers.
0.00000734 - 0.0000466 = -0.00003926
Step 3: Express the result in scientific notation.
-0.00003926 can be written as -3.926 * 10^-5.
Therefore, the answer is -3.926 * 10^-5.
To subtract 4.66 * 10^-5 - 7.34 * 10^-7, we need to first express both numbers in scientific notation.
4.66 * 10^-5 = 0.0000466 (since 5 is the negative exponent, we shift the decimal point five places to the left.)
7.34 * 10^-7 = 0.000000734 (since 7 is the negative exponent, we shift the decimal point seven places to the left.)
Now, we can subtract these two numbers:
0.0000466 - 0.000000734 = 0.000045866
To express this result in scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, and determine the new exponent based on the number of places we moved the decimal point.
In this case, we move the decimal point four places to the right:
0.000045866 = 4.5866 * 10^-5
So, the correct answer is - 4.5866 * 10^-5.
