Scientific Notation

Area: 1/2πr2

Perimeter: 1/2πd+d

Four hundred seven ten-thousandths (0.0407) in standard form is 4.07 × 10-2

0.0452 = 4.52 × 10-2

It is 1.6*10^5.

It is 4.2*10^3

The number 20.7 million (20,700,000) can be put into scientific notation by remembering that we want a decimal with the leading (or first digit) between 1 and 10. So we would count how many places to the left we'd move the decimal, in this case seven. Because we're moving it to the left, our exponent will be positive; if we were moving it to the right, our exponent would have to be negative. So in this case, our answer would be 2.07 x 10^7.

The idea is to save page space and time. Instead of writing out a 1 followed by 100 zeros for a google (which would take up a long time and a lot of space) you simply write 10^100.

It can, depending on the values being manipulated, also facilitate arithmetic by turning multiplying or dividing the powers into adding or subtracting the indices (the principle of the logarithm).

82700000000 = 8.27x1010

1.4565 x 10^4

It is: 5.601*103

43470 = 4.3470*104

43470 = 4.3470*104

43470 = 4.3470*104

43470 = 4.3470*104

462 x 10^-3 if I´m not mistaken ;-)

Note that something that is a billion has base 109. Then, 17 billion is 17 x 109. Finally, move a decimal place to the left to get:

1.7 X 1010

2.3400e4

If you mean 70,000 then it is 7.0*10^4 in scientific notation

3.02 x 10^8

5.48x106

7.7812 × 108

or

7.7812E8

It is: 6.34*10^5

The scientific notation of .0014 is 1.4*10-3

34 in Scientific Notation = 3.4 x 101

6x10^-6

9.63 X 10

7

5.123x10-3.
