To compare which star is farther away, we need to compare the exponents of the distances. The exponent for star A is 3, while the exponent for star B is 5. Since 5 is greater than 3, star B is farther away.
To find the difference in standard notation, we subtract the exponent of star A from the exponent of star B: 5 - 3 = 2.
Therefore, star B is farther away by a difference of 10^2, which is 100 in standard notation.
The distance to star A is about 8x10^3 light years. The distance to Star B is about 6x10^5 light years. Find which star is farther away. Then find by how much in standard notation.
