Add. Write your answer in scientific notation. (1.41 * 10^6) + (5.9 * 10^6) Choices: (A)7.31 * 10^7 (B)7.31 * 10^6 (C)8.319 * 10^6 (D)8.319 * 10^7

Add Coefficients: We have the following numbers to add: (1.41 * 10^6) + (5.9 * 10^6) Since the exponents of 10 are the same, we can directly add the coefficients. What is 1.41 + 5.9? 1.41 + 5.9 = 7.31Write in Scientific Notation: Write the answer in scientific notation. Since we have added the coefficients, we keep the exponent the same. Scientific notation: 7.31 * 10^6Find Equivalent Expression: Choose the equivalent expression for (1.41 * 10^6) + (5.9 * 10^6). (1.41 * 10^6) + (5.9 * 10^6) = 7.31 * 10^6 Therefore, the sum in scientific notation is 7.31 * 10^6.

Add Coefficients: We have the following numbers to add: $\newline$ $(1.41 \times 10^6) + (5.9 \times 10^6)$ $\newline$ Since the exponents of $10$ are the same, we can directly add the coefficients. $\newline$ What is $1.41 + 5.9$ ? $\newline$ $1.41 + 5.9 = 7.31$
Write in Scientific Notation: Write the answer in scientific notation. $\newline$ Since we have added the coefficients, we keep the exponent the same. $\newline$ Scientific notation: $7.31 \times 10^6$
Find Equivalent Expression: Choose the equivalent expression for $(1.41 \times 10^6) + (5.9 \times 10^6)$ . $(1.41 \times 10^6) + (5.9 \times 10^6) = 7.31 \times 10^6$ Therefore, the sum in scientific notation is $7.31 \times 10^6$ .
