A grain of ragweed pollen is 0.00002 meters in diameter. What is the diameter using scientific notation? \( 2 \times 10^{5} \) meters \( 0.2 \times 10^{4} \) meters \( 2 \times 10^{-5} \) meters \( 0.2 \times 10^{-4} \) meters

The diameter of a grain of ragweed pollen is 0.00002 meters, which can be expressed in scientific notation as \( 2 \times 10^{-5} \) meters. This notation makes it easier to handle very small or very large numbers, especially in scientific and mathematical calculations. When it comes to working with scientific notation, a common mistake is misplacing the decimal point or confusing the exponents. Remember that the exponent indicates how many places to move the decimal point. For example, in \( 2 \times 10^{-5} \), you would shift the decimal point five places to the left to return to the standard decimal form. Keep practicing, and you'll master it in no time!
