how would I find a reasonable estimate of 7.4 x 10^6 ÷ 6.8 x 10^-6 in correct scientific notation to 1 significant figure
+181 \(\frac{7.4*10^6}{6.8*10^-6} = \frac{7.4}{6.8}*\frac{10^6}{10^-6}\)
7.4 / 6.8 is approximately 1.088. This multiplied by the second part is 1.088 * 10^12. After rounding to 1 significant figure, you would get 1 * 10^12
