Answer: <u><em>2.03259656 × 10^8</em></u>
Explanation:
1.5 x 10 = 15
√(15) = <em>3.87</em>
<u><em>put this to the side until we sum everything up..</em></u>
3.5 × 10 = 35
35 ^ 5 = <em>52521875</em>
So, now lets sum it all up....
(3.87) x (52521875) = <u><em>203259656.25</em></u>
but in scientific notation it is: <u><em>2.03259656 × 10^8</em></u>
