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.
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
