How do you translate scientific notation to ordinary numbers?

Answer 1

S.N. uses a number greater than 1, less than 10 ( 10>n>1), and a power of ten.

To convert, simply move the decimal point (d.p.) the number of places shown by the power of ten.

For a positive power of ten, shift right, for a negative power of ten, shift left (and add zeroes if needed).

Strictly speaking, 30.15 x 102, 956 x 10-3 are not S.N., as the number is not <10,

and > 1

Examples. 2.05 x 103 means shift the d.p. 3 places to the right:

20.5 - one place,

205 - two places,

2050 - three places.

7.56 x 10-4 means shift the d.p. 4 places left:

0.756 - one place,

0.0756 - two places,

0.007 56 - three places (and group digits into bunches of three for legibility),

0.000 756 - four places.
