Subtract. Write your answer in scientific notation. (8.97 * 10^2) - (5 * 10^2) Choices: (A)8.4 * 10^3 (B)8.4 * 10 (C)3.97 * 10^2 (D)3.97 * 10^0

Calculate Coefficients: We have: (8.97 * 10^2) - (5 * 10^2) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 8.97 - 5? 8.97 - 5 = 3.97Convert to Scientific Notation: Write the answer in scientific notation. Substitute 3.97 for the coefficient and 2 for the exponent in a * 10^b. Scientific notation: 3.97 * 10^2Find Equivalent Expression: Choose the equivalent expression for (8.97 * 10^2) - (5 * 10^2). (8.97 * 10^2) - (5 * 10^2) = 3.97 * 10^2 (8.97 * 10^2) - (5 * 10^2) is equivalent to 3.97 * 10^2.

\newline

(B)

8.4 \times 10

\newline

(C)

3.97 \times 10^2

\newline

(D)

3.97 \times 10^0

Calculate Coefficients: We have: $\newline$ $(8.97 \times 10^2) - (5 \times 10^2)$ $\newline$ Since the powers of $10$ are the same, we can subtract the coefficients directly. $\newline$ What is $8.97 - 5$ ? $\newline$ $8.97 - 5 = 3.97$
Convert to Scientific Notation: Write the answer in scientific notation. $\newline$ Substitute $3.97$ for the coefficient and $2$ for the exponent in $a \times 10^b$ . $\newline$ Scientific notation: $3.97 \times 10^2$
Find Equivalent Expression: Choose the equivalent expression for $(8.97 \times 10^2) - (5 \times 10^2)$ . $(8.97 \times 10^2) - (5 \times 10^2) = 3.97 \times 10^2$ $(8.97 \times 10^2) - (5 \times 10^2)$ is equivalent to $3.97 \times 10^2$ .
