(4.18 x 10^-4)(9 x 10^-4)
= (4.18 x 9)(10^-4 x 10^-4)
= 37.62 x 10^-8
= 3.762 x 10^-7

4)
(9.45 x 10^10) / (1.5 x 10^6)
=(9.45 / 1.5) (10^10 / 10^6)
= 6.3 x 10^4

6)
(9 x 10^-11) / (2.4 x 10^8)
= (9 / 2.4) (10^-11 / 10^8)
= 3.75 x 10^-19

8)
(9.5 x 10^11) + (6.3 x 10^9)
= 10^9 (950 + 6.3)
= 956.3 x 10^9
= 9.563 x 10^11

10)
(1.357 x 10^9) + 590,000
= (1.357 x 10^9) + (5.9 x 10^5)
= 10^5 (13,570 + 5.9)
=13,575.9 x 10^5
= 1.35759 x 10^9
