<u>7.022</u>
Explanation:
2.589x10^6/
3.687x10^5
<u>1. </u> 2.589/3.687 = 0.702197 <em><u> [Separate out and divide just the decimal portion first]</u></em>
<u>2.</u> 10^6/10^5 = 10^(6-5) = 10^1 <em><u>[Divide the exponent portion next]</u></em> When dividing, subtract the denominator exponent from the numerator exponent: (6-5) = 1. The exponent is 1.
0.702197x10^1 <em><u>[Put the two pieces together: 1. and 2.]</u></em>
7.02197 <em><u> [Move the decimal point once to the right, which will reduce 10^1 to 10^0, or 1]</u></em>
<h2><u>
7.02197 or 7.022 to 4 sig figs</u></h2>
