Add. Write your answer in scientific notation. (3.2 * 10^2) + (4.047 * 10^2) Choices: (A)7.247 * 10^2 (B)9.74 * 10^4 (C)7.247 * 10^4 (D)9.74 * 10^2

Identify Given Numbers: We have: (3.2 * 10^2) + (4.047 * 10^2) Since the powers of 10 are the same, we can directly add the coefficients. What is 3.2 + 4.047? 3.2 + 4.047 = 7.247Add Coefficients: Write the answer in scientific notation. Substitute 7.247 for the coefficient and 2 for the exponent in a * 10^b. Scientific notation: 7.247 * 10^2Convert to Scientific Notation: Choose the equivalent expression for (3.2 * 10^2) + (4.047 * 10^2). (3.2 * 10^2) + (4.047 * 10^2) = 7.247 * 10^2 (3.2 * 10^2) + (4.047 * 10^2) is equivalent to 7.247 * 10^2.

Identify Given Numbers: We have: $\newline$ $(3.2 \times 10^2) + (4.047 \times 10^2)$ $\newline$ Since the powers of $10$ are the same, we can directly add the coefficients. $\newline$ What is $3.2 + 4.047$ ? $\newline$ $3.2 + 4.047 = 7.247$
Add Coefficients: Write the answer in scientific notation. $\newline$ Substitute $7.247$ for the coefficient and $2$ for the exponent in $a \times 10^b$ . $\newline$ Scientific notation: $7.247 \times 10^2$
Convert to Scientific Notation: Choose the equivalent expression for $(3.2 \times 10^2) + (4.047 \times 10^2)$ . $(3.2 \times 10^2) + (4.047 \times 10^2) = 7.247 \times 10^2$ $(3.2 \times 10^2) + (4.047 \times 10^2)$ is equivalent to $7.247 \times 10^2$ .
