Q. Multiply.

\newline

(1 \times 10^1)(4 \times 10^2)

\newline

Choices:

\newline

(A)

6 \times 10^3

\newline

(B)

4 \times 10^4

\newline

(C)

4 \times 10^2

\newline

(D)

4 \times 10^3

Group Terms: We have the expression $1 \times 10^1$ $(4 \times 10^2)$ . First, we need to group the coefficients and the power terms together. $\newline$ Coefficients: $1$ and $4$ $\newline$ Power terms: $10^1$ and $10^2$
Multiply Coefficients: Multiply the coefficients together. $\newline$ $1 \times 4 = 4$
Multiply Power Terms: Multiply the power terms together. When multiplying powers with the same base, we add the exponents. $\newline$ $10^1 \times 10^2 = 10^{(1 + 2)} = 10^3$
Combine Results: Combine the results from Step $2$ and Step $3$ to write the final answer in scientific notation. $\newline$ Coefficient = $4$ $\newline$ Power term = $10^3$ $\newline$ Scientific notation: $4 \times 10^3$
