What is 5.5×10^4 multiplied by 2.2×10^−8 ? Write the answer in scientific notation
To multiply numbers in scientific notation, we 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
The answer in scientific notation is 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^(-12)
Therefore, the answer in scientific notation is:
12.1 × 10^(-12)
To multiply numbers written in scientific notation, we multiply the coefficients (the numbers before the powers of 10) and add the exponents.
Given:
5.5 × 10^4 multiplied by 2.2 × 10^-8
Step 1: Multiply the coefficients:
5.5 × 2.2 = 12.1
Step 2: Add the exponents:
10^4 × 10^-8 = 10^(4 - 8) = 10^-4
Step 3: Combine the coefficient and the exponent in scientific notation:
12.1 × 10^-4
Therefore, the answer is 12.1 × 10^-4 in scientific notation.
