Question

The distance between earth and the moon is 384 000 kilometer, express this in scientific notation

Answer 1

to put a number in scientific notation means using a power of 10, and formatting the number with only one integer to the left of the decimal point.

384000. will turn to 3.84000, if we moved the decimal point to the left by 5 slots, then that's the exponent of the 10, therefore 3.84000 x 10⁵ or just 3.84 x 10⁵.

Answer 2

Cientific notation consists in breaking down the number, and multiplying it by a power of ten.

The scientific notation of 384 000 would be:

$384,000 = \bf~384 * 10^{3}$
