What is 5.5 * 10 ^ 4 multiplied by 2.2 * 10 ^ - 8 Write the answer in scientific notation.
To multiply numbers in scientific notation, you need to multiply their coefficients and add their exponents.
(5.5 * 10^4) * (2.2 * 10^-8) = (5.5 * 2.2) * (10^4 * 10^-8) = 12.1 * 10^-4
Since 12.1 is not in scientific notation, we need to convert it.
12.1 = 1.21 * 10^1
Therefore, the final answer in scientific notation is 1.21 * 10^-3.
To multiply numbers in scientific notation, we follow these steps:
1. Multiply the coefficients: 5.5 * 2.2 = 12.1
2. Add the exponents: 4 + (-8) = -4
Therefore, the answer is 12.1 * 10^-4.
To multiply two numbers written in scientific notation, you can multiply their coefficients and add their exponents. Let's calculate the result step by step:
1. Multiply the coefficients:
5.5 * 2.2 = 12.1
2. Add the exponents:
10^4 * 10^-8 = 10^(4-8) = 10^-4
Now, combine the coefficient and exponent to write the result in scientific notation:
12.1 * 10^-4
Therefore, the answer is 1.21 * 10^-3 in scientific notation.
