Scientific Notation

It is: 7.8112*10^3

3.1 x 10 to the adkfjdklajld jcmcdsjf power

When multiplying exponents, you add them. So, 10^4 x 10^2 = 10^6. Now 6.2 x 3.3 = 20.46. So, you would have 20.46 x10^6, but we want the number in front of the x10 to be less than 10 and greater than 1, so the answer would be 2,046x10^7 (move the decimal one to the left, and increase the exponent by 1).

9.9e-5 or 9.9 x 10^-5

Yes.

1.5 x 10^8 km

It is: 1.55*10^9 in scientific notation

It is: 6.2*109

6 x 10 to the power of 9

3.4*108

0.0000000000011 in scientific notation is: 1.1 x 10^-12

1.23x10-5 in scientific notation is 1.23 x 10-5

This equates to 0.0000123 in standard notation.

Scientific notation is is a great way to shorten long numbers. When you use scientific notation, you are counting the number of place the decimal has to move in order to get the short form of the number. For 1 billion, it would be 1 x 10^9 because the decimal point had to shift 9 times.

9.19263177 (usually you would round this to 9.19) x 10^9.

2.89*10-3

0.00325 = 3.25 x 10-3

7.78*10-3

The number of digits in the coefficient should be exactly the same as the number of significant figures.

It is: 5.48*10^-5

It is 6.86*10^5 in scientific notation

8.2 x 10^-1

In scientific notation it is 1.57821*10^5 and so it is 10 to the power of 5

1.86 x 10^5 miles per second (approximate)
