Subtract. Write your answer in scientific notation. (8.11 * 10^7) - (4.3 * 10^7) Choices: (A)3.81 * 10^7 (B)4.38 * 10^7 (C)4.88 * 10^7 (D)3.41 * 10^7

Identify Coefficients: We have: (8.11 * 10^7) - (4.3 * 10^7) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 8.11 - 4.3? 8.11 - 4.3 = 3.81Convert to Scientific Notation: Write the answer in scientific notation. Substitute 3.81 for the coefficient and 7 for the exponent in a * 10^b. Scientific notation: 3.81 * 10^7Find Equivalent Expression: Choose the equivalent expression for (8.11 * 10^7) - (4.3 * 10^7). (8.11 * 10^7) - (4.3 * 10^7) = 3.81 * 10^7 (8.11 * 10^7) - (4.3 * 10^7) is equivalent to 3.81 * 10^7.

Identify Coefficients: We have: $\newline$ $(8.11 \times 10^7) - (4.3 \times 10^7)$ $\newline$ Since the powers of $10$ are the same, we can subtract the coefficients directly. $\newline$ What is $8.11 - 4.3$ ? $\newline$ $8.11 - 4.3 = 3.81$
Convert to Scientific Notation: Write the answer in scientific notation. $\newline$ Substitute $3.81$ for the coefficient and $7$ for the exponent in $a \times 10^b$ . $\newline$ Scientific notation: $3.81 \times 10^7$
Find Equivalent Expression: Choose the equivalent expression for $(8.11 \times 10^7) - (4.3 \times 10^7)$ . $\newline$ $(8.11 \times 10^7) - (4.3 \times 10^7) = 3.81 \times 10^7$ $\newline$ $(8.11 \times 10^7) - (4.3 \times 10^7)$ is equivalent to $3.81 \times 10^7$ .
