Scientific notation

Question

Write two hundred-thousandths in scientific notation.

Answer 1

two hundred-thousandths

 

= 2 * 1/100000

 

= 2 * 10^(-5)

 

This page, http://en.wikipedia.org/wiki/List_of_numbers, says,
0.00001 = 1/10^5 = One hundred-thousandth.

Following their example, I’d say two hundred-thousandths = 0.00002 = 2(10^(-5)), as I stated.

 

Here are the decimal names up to 10^(-9):

0.1
One tenth, [zero] point one
0.01
One hundredth, [zero] point zero one
0.001
One thousandth, [zero] point zero zero one
0.000 1
One ten-thousandth, [zero] point zero zero zero one
0.000 01
One hundred-thousandth
0.000 001
One millionth
0.000 000 1
One ten-millionth
0.000 000 01
One hundred-millionth
0.000 000 001
One billionth (in some dialects)

So 0.000 02 is Two hundred-thousandths since
0.000 01 is One hundred-thousandths.

Since 0.001 is One thousandth,
200 of them would be 0.200 = Two Hundred thousandths.

The hyphen is important.

Always state the actual number; English is so prone to confusion.

Answer 2

Write two hundred-thousandth in Scientific Notation

 

The key here is the -th at the end of thousandth

in decimal notation this is 0.200

 

or ;   2.00 x 10^-1

 

 

 

Answer 3

Simply you allow one digit for whole number part multiplied by 10^m

 

  225 = 2. 25 * 10 ^2

 

   35497.26 = 3.54 9726 * 10 ^ 4

 

     0.  0035 = 3.5 X10 ^ -3
