Report with correct significant figures in scientific notation <br>3.698 X 10^4÷1.85 X 10^2

Alina [70]

Answer:

$2.00x10^2$

Explanation:

Hello!

In this case, we need to keep in mind that performing these types of operations require that the final result was shown with the same significant figures as the initial number with the fewest ones; it means, we show the final result with 3 significant figures, because 3.698 has four and 1.85 has three significant figures; therefore, we obtain:

$3.698 x 10^4/1.85x10^2\\\\2.00x10^2$

Best regards!
