Subtract. Write your answer in scientific notation. (4.9 * 10^8) - (2.39 * 10^8) Choices: (A)5.71 * 10^8 (B)2.51 * 10^8 (C)4.84 * 10^8 (D)6.03 * 10^8

Identify Subtraction Problem: We have the following subtraction problem: (4.9 * 10^8) - (2.39 * 10^8) Since the powers of 10 are the same, we can directly subtract the coefficients. What is 4.9 - 2.39? 4.9 - 2.39 = 2.51Perform Subtraction: Write the answer in scientific notation. Substitute 2.51 for the coefficient and 8 for the exponent in a * 10^b. Scientific notation: 2.51 * 10^8Convert to Scientific Notation: Choose the equivalent expression for (4.9 * 10^8) - (2.39 * 10^8). (4.9 * 10^8) - (2.39 * 10^8) = 2.51 * 10^8 (4.9 * 10^8) - (2.39 * 10^8) is equivalent to 2.51 * 10^8.

Identify Subtraction Problem: We have the following subtraction problem: $\newline$ $(4.9 \times 10^8) - (2.39 \times 10^8)$ $\newline$ Since the powers of $10$ are the same, we can directly subtract the coefficients. $\newline$ What is $4.9 - 2.39$ ? $\newline$ $4.9 - 2.39 = 2.51$
Perform Subtraction: Write the answer in scientific notation. $\newline$ Substitute $2.51$ for the coefficient and $8$ for the exponent in $a \times 10^b$ . $\newline$ Scientific notation: $2.51 \times 10^8$
Convert to Scientific Notation: Choose the equivalent expression for $(4.9 \times 10^8) - (2.39 \times 10^8)$ . $(4.9 \times 10^8) - (2.39 \times 10^8) = 2.51 \times 10^8$ $(4.9 \times 10^8) - (2.39 \times 10^8)$ is equivalent to $2.51 \times 10^8$ .
