Scientific Notation

Question

I have to convert 6168 billion km into meters with scientific notation, I don't know if the power is

6,168 × 10^15 or ^18

😭😅

Answer 1

6168 billion

1 thousand = 10^3 = 1,000, 1 with 3 zeros

1 million = 10^6 = 1,000,000 1 with 6 zeros

1 billion = 10^9 = 1,000,000,000 1 with 9 zeros

6,168 billion = = 6,168 x 10^9

or in scientific notations:

= 6.168 x 10^12 km

but no exponents with 15 or 18

unless you meant trillions or quadrillons
