Full solution

Q. Multiply. Write your answer in scientific notation.

\newline

(1 \times 10^5)(4 \times 10^1)

\newline

______

Group Coefficients and Powers: We have: $\newline$ $(1 \times 10^5)(4 \times 10^1)$ $\newline$ Group the coefficients and power terms together. $\newline$ Coefficients: $1$ and $4$ $\newline$ Power terms: $10^5$ and $10^1$
Multiply Coefficients: What is $1 \times 4$ ? Multiply the coefficients. $\newline$ $1 \times 4 = 4$
Combine Power Terms: Write $10^5 \times 10^1$ as a single power of $10$ . When multiplying powers with the same base, we add the exponents. $\newline$ $10^5 \times 10^1$ $\newline$ $= 10^{5 + 1}$ $\newline$ $= 10^6$
Final Scientific Notation: We found: $\newline$ Coefficient = $4$ $\newline$ Power term = $10^6$ $\newline$ Write the final answer in scientific notation. Substitute $4$ for $a$ and $6$ for $b$ in $a \times 10^b$ . $\newline$ Scientific notation: $4 \times 10^6$
