Q. How do you write

78

in scientific notation?

\newline

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

Identify Significant Digit: Identify the most significant digit and the decimal point's position in the number $78$ . The most significant digit is $7$ , and the decimal point in $78$ is after the last digit, so it's $78.0$ .
Move Decimal Point: Move the decimal point to the right of the first non-zero digit to create a number between $1$ and $10$ . Moving the decimal point between $7$ and $8$ , we get $7.8$ .
Count Decimal Point Places: Count the number of places the decimal point has moved to determine the exponent of $10$ . The decimal point has moved $1$ place to the left, so the exponent will be positive $1$ .
Write in Scientific Notation: Write the number in scientific notation using the number from Step $2$ and the exponent from Step $3$ . $\newline$ The scientific notation of $78$ is $7.8 \times 10^1$ .
