Multiply. Write your answer in scientific notation. (2 * 10^5)(2 * 10^3) ______

Group Coefficients and Power Terms: We have: (2 × 10^5)(2 × 10^3) Group the coefficients and power terms together. Coefficients: 2 and 2 Power terms: 10^5 and 10^3Multiply Coefficients: What is 2 × 2? Multiply the coefficients. 2 × 2 = 4Combine Power Terms: Write 10^5 × 10^3 as a single power of 10. When multiplying powers with the same base, we add the exponents. 10^5 × 10^3 = 10^(5 + 3) = 10^8Write Final Answer: We found: Coefficient = 4 Power term = 10^8 Write the final answer in scientific notation. Substitute 4 for a and 8 for b in a × 10^b. Scientific notation: 4 × 10^8

\newline

(2 \times 10^5)(2 \times 10^3)

Group Coefficients and Power Terms: We have: $\newline$ $(2 \times 10^5)(2 \times 10^3)$ $\newline$ Group the coefficients and power terms together. $\newline$ Coefficients: $2$ and $2$ $\newline$ Power terms: $10^5$ and $10^3$
Multiply Coefficients: What is $2 \times 2$ ? Multiply the coefficients. $\newline$ $2 \times 2 = 4$
Combine Power Terms: Write $10^5 \times 10^3$ as a single power of $10$ . When multiplying powers with the same base, we add the exponents. $\newline$ $10^5 \times 10^3$ $\newline$ $= 10^{(5 + 3)}$ $\newline$ $= 10^8$
Write Final Answer: We found: $\newline$ Coefficient = $4$ $\newline$ Power term = $10^8$ $\newline$ Write the final answer in scientific notation. Substitute $4$ for $a$ and $8$ for $b$ in $a \times 10^b$ . $\newline$ Scientific notation: $4 \times 10^8$
