What is 5.5 * 10 ^ 4 multiplied by 2.2 * 10 ^ - 8 ? Write the answer in scientific notation. (1 point)
O 12.1 * 10 ^ - 4
O 1.21 * 10 ^ - 5
O 1.21 * 10 ^ - 4
O 1.21 * 10 ^ - 3
To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents.
First, multiply the coefficients:
5.5 * 2.2 = 12.1
Then, add the exponents:
10^4 * 10^-8 = 10^(4-8) = 10^-4
Therefore, the answer in scientific notation is 12.1 * 10^-4, which corresponds to option O 12.1 * 10^-4.
Are you sure?
To multiply numbers in scientific notation, you need to multiply the coefficients (5.5 * 2.2) and add the exponents (4 + (-8)).
The product of the coefficients is 5.5 * 2.2 = 12.1.
The sum of the exponents is 4 + (-8) = -4.
Thus, the final answer in scientific notation is 12.1 * 10 ^ -4.
Therefore, the correct answer is: O 12.1 * 10 ^ -4.
To multiply numbers in scientific notation, you can multiply the decimal parts together and add the exponents.
First, multiply the decimal parts: 5.5 * 2.2 = 12.1.
Then, add the exponents: 10^4 * 10^-8 = 10^(4 + (-8)) = 10^-4.
So, the answer is 12.1 * 10^-4, which is equivalent to 1.21 * 10^-3.
Therefore, the correct answer is O 1.21 * 10 ^ -3.
