Write 0.000765 in standard form?

Question

MODULE M8-SECTION B

Answer 1

Find the first non-zero digit (7) and move the decimal point there:

0.000765 --> 7.65

Now count the number of places you moved the decimal. If you moved it left, count positive. If you moved it right (like in this example) count negative. You get -4 places.

So converted to standard (scientific notation) form:

0.000765 ---> 7.65 x 10^(-4)

(That's 10 to the -4 power = 1/10000, which makes sense).

Answer 2

0.000765
count up how many decimal places you need until you have a number that has only 1 unit before the decimal...in this case there are 4. so 0.000765 = 7.65x10^-4
if it is 10 to the power a negative number, that means you are moving the decimal forward from the number not behind the number, hence its a smaller number than 1.

Answer 3

7.65x10^-4

to write in standard form the nomber has to be betwan 1 and 10 but not inclooding 10 then uo times by 10 to the power what ever to get the nomber you oridionaly had

Answer 4

7.65 x 10 to the power -4 (cant do the small -4 on this site)

Answer 5

7.65 x 10 to the power -4.

Answer 6

3.87 x 10^(-3) for conventional variety you write the huge sort so it fairly is a decimal between a million and 10 (yet not equivalent to ten), and then write it as more advantageous by using 10 to the potential of how many areas you necessary to bypass the decimal element to get it to that variety. working example, above, you ought to bypass the decimal element spectacular 3 areas, so it fairly is to the potential of -3 . shifting spectacular is destructive, left advantageous.

Answer 7

7.65 x 10^(-4) is correct but some people e.g. engineers would prefer it as 0.765 x 10^(-3) or 765 x 10^(-6)

Answer 8

7.65 x 10^-4

Answer 9

7.65 x 10^-4

Answer 10

0.000765 = 7.65 x 10^(-4)
