Add. Write your answer in scientific notation. (2.39 * 10^2) + (5.04 * 10^2) Choices: (A)7.43 * 10^2 (B)8.04 * 10^4 (C)7.43 * 10^4 (D)8.04 * 10^2

Given Expression: We have: (2.39 * 10^2) + (5.04 * 10^2) Since the powers of 10 are the same, we can directly add the coefficients. What is 2.39 + 5.04? 2.39 + 5.04 = 7.43Add Coefficients: Write the answer in scientific notation. Substitute 7.43 for the coefficient and 2 for the exponent in a * 10^b. Scientific notation: 7.43 * 10^2Write in Scientific Notation: Choose the equivalent expression for (2.39 * 10^2) + (5.04 * 10^2). (2.39 * 10^2) + (5.04 * 10^2) = 7.43 * 10^2 (2.39 * 10^2) + (5.04 * 10^2) is equivalent to 7.43 * 10^2.

(2.39 \times 10^2) + (5.04 \times 10^2)

Given Expression: We have: $\newline$ $(2.39 \times 10^2) + (5.04 \times 10^2)$ $\newline$ Since the powers of $10$ are the same, we can directly add the coefficients. $\newline$ What is $2.39 + 5.04$ ? $\newline$ $2.39 + 5.04 = 7.43$
Add Coefficients: Write the answer in scientific notation. $\newline$ Substitute $7.43$ for the coefficient and $2$ for the exponent in $a \times 10^b$ . $\newline$ Scientific notation: $7.43 \times 10^2$
Write in Scientific Notation: Choose the equivalent expression for $(2.39 \times 10^2) + (5.04 \times 10^2)$ . $(2.39 \times 10^2) + (5.04 \times 10^2) = 7.43 \times 10^2$ $(2.39 \times 10^2) + (5.04 \times 10^2)$ is equivalent to $7.43 \times 10^2$ .
