What is 5.5×104 multiplied by 2.2×10−8 ? Write the answer in scientific notation.
To multiply numbers in scientific notation, you multiply the coefficients (5.5 × 2.2) and add the exponents (4 + (-8)).
5.5 × 2.2 = 12.1
The exponent will be the sum of the exponents, which is -4.
Therefore, the answer in scientific notation is 12.1 × 10^-4.
To multiply numbers in scientific notation, multiply the coefficients and add the exponents.
(5.5 × 10^4) × (2.2 × 10^-8)
= (5.5 × 2.2) × (10^4 × 10^-8)
= 12.1 × 10^(-4+(-8)) [Multiplying the coefficients and adding the exponents]
= 12.1 × 10^-12
Therefore, the answer in scientific notation is 1.21 × 10^-11.
To multiply numbers written in scientific notation, you can simply multiply the coefficients (the numbers before the powers of 10) and add the exponents. Here's how you can solve the problem 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.
Therefore, the answer in scientific notation is 12.1 × 10^-4.
please explain
Apologies for the confusion. Let's go through the steps to multiply the numbers in scientific notation once again:
1. Multiply the coefficients: 5.5 × 2.2 = 12.1.
2. Multiply the powers of 10 by adding their exponents: (10^4) × (10^-8) = 10^(4 + (-8)) = 10^(-4).
To clarify further, when multiplying numbers in scientific notation, you can simply multiply the coefficients and add the exponents.
Therefore, 5.5×10^4 multiplied by 2.2×10^-8 is equal to 12.1×10^-4, which is written in scientific notation as 1.21×10^-3.
