Subtract. Write your answer in scientific notation. (6.63 * 10^6) - (2.6 * 10^6) Choices: (A)4.03 * 10^8 (B)4.03 * 10^6 (C)4.03 * 10^4 (D)4.03 * 10^2

Calculate Coefficients: We have: (6.63 * 10^6) - (2.6 * 10^6) Since the powers of 10 are the same, we can subtract the coefficients directly. What is 6.63 - 2.6? 6.63 - 2.6 = 4.03Convert to Scientific Notation: Write the answer in scientific notation. Substitute 4.03 for the coefficient and 6 for the exponent in a * 10^b. Scientific notation: 4.03 * 10^6Find Equivalent Expression: Choose the equivalent expression for (6.63 * 10^6) - (2.6 * 10^6). (6.63 * 10^6) - (2.6 * 10^6) = 4.03 * 10^6 (6.63 * 10^6) - (2.6 * 10^6) is equivalent to 4.03 * 10^6.

\newline

Choices:

\newline

(A)

4.03 \times 10^8

\newline

(B)

4.03 \times 10^6

\newline

(C)

4.03 \times 10^4

\newline

(D)

4.03 \times 10^2

Calculate Coefficients: We have: $\newline$ $(6.63 \times 10^6) - (2.6 \times 10^6)$ $\newline$ Since the powers of $10$ are the same, we can subtract the coefficients directly. $\newline$ What is $6.63 - 2.6$ ? $\newline$ $6.63 - 2.6 = 4.03$
Convert to Scientific Notation: Write the answer in scientific notation. $\newline$ Substitute $4.03$ for the coefficient and $6$ for the exponent in $a \times 10^b$ . $\newline$ Scientific notation: $4.03 \times 10^6$
Find Equivalent Expression: Choose the equivalent expression for $(6.63 \times 10^6) - (2.6 \times 10^6)$ . $(6.63 \times 10^6) - (2.6 \times 10^6) = 4.03 \times 10^6$ $(6.63 \times 10^6) - (2.6 \times 10^6)$ is equivalent to $4.03 \times 10^6$ .
