Q. How do you write

18.7

in scientific notation?

\newline

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

Move Decimal Point: To write a number in scientific notation, we need to express it as a number between $1$ and $10$ multiplied by a power of $10$ . We do this by moving the decimal point to the left until only one non-zero digit is to the left of the decimal point. For $18.7$ , we move the decimal point one place to the left. $\newline$ Calculation: $18.7$ becomes $1.87$ . $\newline$ Math error check:
Calculate Power of $10$ : Now that we have the number $1.87$ , which is between $1$ and $10$ , we need to determine the power of $10$ that will give us back the original number when multiplied by $1.87$ . Since we moved the decimal point one place to the left, the power of $10$ is $1$ . $\newline$ Calculation: $1.87 \times 10^1 = 18.7$ . $\newline$ Math error check:
