Subtract. Write your answer in scientific notation. (7.12 * 10^3) - (4.43 * 10^3) Choices: (A)9.18 * 10^3 (B)2.69 * 10^3 (C)5.72 * 10^3 (D)3.55 * 10^3

Identify Coefficients: We have: (7.12 * 10^3) - (4.43 * 10^3) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 7.12 - 4.43? 7.12 - 4.43 = 2.69Subtract Coefficients: Write the answer in scientific notation. Substitute 2.69 for a and 3 for b in a * 10^b. Scientific notation: 2.69 * 10^3Convert to Scientific Notation: Choose the equivalent expression for (7.12 * 10^3) - (4.43 * 10^3). (7.12 * 10^3) - (4.43 * 10^3) = 2.69 * 10^3 (7.12 * 10^3) - (4.43 * 10^3) is equivalent to 2.69 * 10^3.

\newline

Choices:

\newline

(A)

9.18 \times 10^3

\newline

(B)

2.69 \times 10^3

\newline

(C)

5.72 \times 10^3

\newline

(D)

Identify Coefficients: We have: $\newline$ $(7.12 \times 10^3) - (4.43 \times 10^3)$ $\newline$ Since the powers of $10$ are the same, we can subtract the coefficients directly. $\newline$ What is $7.12 - 4.43$ ? $\newline$ $7.12 - 4.43 = 2.69$
Subtract Coefficients: Write the answer in scientific notation. $\newline$ Substitute $2.69$ for $a$ and $3$ for $b$ in $a \times 10^b$ . $\newline$ Scientific notation: $2.69 \times 10^3$
Convert to Scientific Notation: Choose the equivalent expression for $(7.12 \times 10^3) - (4.43 \times 10^3)$ . $(7.12 \times 10^3) - (4.43 \times 10^3) = 2.69 \times 10^3$ $(7.12 \times 10^3) - (4.43 \times 10^3)$ is equivalent to $2.69 \times 10^3$ .
