a chemical reaction produces 3.5 x 10^4 kilograms of product a and 2.2 x 10^3 of product b. how many kilograms of products are produced in total? express your answer in scientific notation.
Answer
Explanation:
Step1: Convert a number to the same exponent
Convert $2.2\times10^{3}$ to a number with an exponent of 4. $2.2\times10^{3}=0.22\times10^{4}$.
Step2: Sumar los dos números
Sum $3.5\times10^{4}$ and $0.22\times10^{4}$. $(3.5 + 0.22)\times10^{4}=3.72\times10^{4}$.
Answer:
$3.72\times10^{4}$
