Multiply. Write your answer in scientific notation. (2 * 10^4)(4 * 10^4) ______

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

(2 \times 10^4)(4 \times 10^4)

\newline

______

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