Scientific Notation

It is: 7.89*10^14

It is: 1.26*10^-3

4*106m + 3*105m = 4*106m + 0.3*106m = 4.3*106m

600,000 = 6.0 × 105

273 = 2.73 × 102

64x10-4

.8 million=8*10^5

9.234 times 103.

7 times 105.

The term is first expressed as 800000000.0. Move 8 decimal places to the left from the starting point and write out:

8.0 x 108

Not sure what pi-co is, but if you mean the prefix pico, for SI units, the answer is 10-12.

7.4 x 10^9

It is 4.265*10^3 in scientific notation

30000

It varies from 2.25*10^5 miles to 2.52*10^5 miles from earth depending on its position of orbit around the earth

It is: 6.55*10^5

9.876 x 10^-5

7.5 x 103.

5,120 in Scientific Notation = 5.12 x 103

1.56611 X 106

Zero superfluous, but will reappear when number is written out.

5.4768 X 103

=========

579,000,000 in Scientific Notation = 5.79 x 108

100 is same as 100.0. Move 2 decimal places left from the starting point, and therefore 100 in Scientific Notation is 1 x 102

273 = 2.73 × 102
