Scientific Notation

7.001 x 10^3

It is: 426.7 rounded to the tenths place because 0.03 is less than 0.05

If the number was 426.75 then it would round to 426.8 in the tenths place

7.97 x 104

3.16 x 10-5.

340,000 = 3.4e+5

This question is of particular interest because the person asking it is under the mistaken impression that scientific notation is one word and not two.

1.98 x 109

0.00000571 in Scientific Notation = 5.71 x 10-6

It is 1.1205*10^5.

8.53 x 10^-6

It is: 3.2*10^13

1.2 × 10-9

I'm assuming you have some idea what scientific notation is, hence, i shall not completely explain it, but in a nut shell its;

the number is always under 10. Never more than 9.

It always ends with 10^..... ( ten to the power of "....")

It it's positive, the decimal point moves to the right. if it's negative, it moves to the left.

thats it in a very small nutshell.

103.8 million = 1.038 x 10^8

It is: 9 x 10^6

It is: 1.53*10^-3

8.72 x 10^14

3.8 * 10^14

There is no such number because you can't have two decimal points in a number

60000022 expressed in scientific notation is 6 × 107

452 = 4.52 * 102

15 cubed = 15^3 or (3 x 10^3) + (3 x 10^2) + (7 x 10^1) + (5 x 10^0)

It is: 1.3*10^7

508000000 = 5.08 × 10^8

I guess you mean the 5.08 bit.

3.054 × 10-2 g

or

3.054E-2g
