a) Adding 3.2 x 104 and 1.95 x 106:
(3.2 x 104) + (1.95 x 106) = 19.5 x 105 + 3.2 x 104
= 19.5 x 105 + 0.32 x 106
= (19.5 + 0.32) x 105
= 19.82 x 105
In scientific notation: 1.982 x 106
b) Subtracting 3.2 x 104 from 1.95 x 106:
(1.95 x 106) - (3.2 x 104) = 19.5 x 105 - 0.32 x 105
= (19.5 - 0.32) x 105
= 19.18 x 105
In scientific notation: 1.918 x 106
c) Multiplying 3.2 x 104 and 1.95 x 106:
(3.2 x 104) x (1.95 x 106) = (3.2 x 1.95) x (104 x 106)
= 6.24 x 1010
In scientific notation: 6.24 x 1010
d) Dividing 1.95 x 106 by 3.2 x 104:
(1.95 x 106) / (3.2 x 104) = (1.95 / 3.2) x (106 / 104)
≈ 0.609 x 102
In scientific notation: 6.09 x 101
