Q. How do you write

13

in scientific notation?

\newline

\_\_\_\_\_\times 10^{\_\_\_\_\_}

Identify Most Significant Digit: Identify the most significant digit in the number $13$ . The most significant digit in $13$ is $1$ .
Place Decimal Point: Place the decimal point after the most significant digit to create a number between $1$ and $10$ . By placing the decimal after the $1$ , we get $1.3$ .
Count Decimal Point Movement: Count the number of places the decimal point has moved from its original position to the position after the most significant digit. $\newline$ The decimal point in $13$ is implicitly after the $3$ , so it has moved one place to the left to get $1.3$ .
Write Number as Product: Write the number as a product of the number found in Step $2$ and $10$ raised to the power of the number of places the decimal point moved found in Step $3$ . $\newline$ Since the decimal point moved one place, we write $13$ as $1.3 \times 10^1$ .
