Question

How do you write `6,000,550,000` in scientific notation?

Answer 1

#6.00055 X 10^9 or, in programming mode, 6.00055 e+09.

Explanation:

In scientific notation, the integer part is usually the most significant digit ( msd ). Here it is 6, of place value `10^9`.

If some tail-end least significant digits ( lsd ) form a string of zeros (there are 4 zeros here ), they are not shown. Yet, if they are correct digits, they could be included in the display.

So, if necessary, the notation could be 6.000550000 e+09, This is called the exponent-mantissa form.

The mantissa is 6.000550000 and the exponent digits +09 should include sign + or`-`. The exponent `+-d` gives the place value of the msd as `10^(+-d)`. Here, msd is 6, d = +9 and the place value of 6 is `10^9`...
