How many times greater is 1 light year in scientific notation than a 1 astronomical unit? Light year: 9.5 x 10^12 km
AU: 1.5 x 10^8 km

The number of times that 1 light year is greater than 1 astronomical unit in scientific notification is; 6.33 × 10⁴

We are given;

1 light year = 9.5 × 10^(12) km

1 astronomical unit = 1.5 × 10^(8) km

Thus to find out how many times greater 1 light year is than 1 astronomical unit in scientific notation, we will divide 1 light year by 1 astronomical unit.

This gives;

(9.5 × 10^(12))/(1.5 × 10^(8))

>> (9.5/1.5) × 10^(12 - 8)

>> 6.33 × 10⁴
