Scientific Notation

It is 1.56*10^-3.

2400 = 2.4 x 10^3

0.0024 = 2.4 x 10^-3

Move the decimal to the left, positive exponent. Move the decimal to the right, negative exponent.

The exponent of 10 tells you how many places to move the decimal point to the left if it is minus or to the right if it is plus.

It is: 5.08*10^8 in scientific notation and the exponent of 10 is 8

8,000 = 8.0 × 10^3 or 8.0E3

2,200,000 = 2.2 x 10^6

Yes, it would look like this: 0.2 x 10^5 or 0.2E5

9 billion written in scientific notation is: 9 x 10^9

It is: 7.2*10^0

It is: 4.5*10^-6 in scientific notation

It is 6.35*10^5 in scientific notation

It is 5.81*10^-4 in scientific notation

It is: 6.9*10^1 in scientific notation

Yes, although the one is not necessary. You can just write 10^-1 km

It is 7.7*10^-2 in scientific notation

If you mean scientific notation of 2.6*10^5 then it is 260,000

it is used to shorten long numbers like 300,000,000 would be 3x10 to the 8th power

If you mean: 60.200 then it is 6.02*10^1

0.434 in scientific notation is 4.34 x 10^-1

To save writing out very large or very small numbers containing a long line of digits as for example 1,000,000,000,000,000 = 1.0*10^15 in scientific notation

It is: 2.8*10^10 which means 2.8 times 10 to the power of 10

If you mean: 20/1,000,000,000 then it is 2.0*10^-8

It is: 1,560,000,000 or as 1.56*10^9 in scientific notation

3 x 10^9

If you mean in scientific notation then it is: 1.495*10^8
