If star A is third magnitude and star B is fifth magnitude which is brighter and by what factor?
A 3rd magnitude star is brighter than a 5th magnitude star by a factor of 6.25.
Each integer difference of magnitude represents a change in apparent brightness of 2.5 times. Hence, a 3rd magnitude star is 2.5 x 2.5 = 6.25 times brighter than a 5th magnitude star.

Is a third magnitude star 10 times brighter then a 4th magnitude star?
Absolutely. When speaking of the brightness you see from earth, you are speaking of apparent magnitude. When considering the type of star, it's composition, stage, age, size, distance, etc., a star is also assigned an absolute magnitude, so the ranking of the star if seen from similar distances reveals the truth about a star. 3.26 light years away is the assumed distance in ranking stars. A star many times farther away than a second star may appear much brighter than the second star which is much closer, based partially on the various factors mentioned above. The lower the value for a magnitude, the brighter, or more correctly, the more luminous, a star. Thus, a 3.4 is brighter than a 5.1, for example. Long ago the scale was originally an arbitrary ranking based on certain stars that were considered to be the brightest. Since then, stars even brighter have been identified, thus the need to use values even less than zero. Only a handful of stars fall below zero in apparent magnitude. So then it is not significant where in the sky (in what constellation) a star lies, the magnitude value determines the brightness.
Are the brightest stars low or high magnitude?
The brightest stars have a low magnitude. Magnitude is measured on a logarithmic scale where lower numbers indicate brighter objects. The brightest star in the night sky, Sirius, has a magnitude of -1.46.
What is a second magnitude star?
A second magnitude star is a star that is relatively bright in the night sky, typically with an apparent visual magnitude between 1.5 and 2.5. These stars are easily visible to the naked eye and are brighter than third magnitude stars but dimmer than first magnitude stars.

05. What two parameters does the brightness of a star depend on?
The brightness of a star - or apparent magnitude [See related question] is how bright a star is as viewed from Earth. Therefore, if we have two stars of similar luminosity but one is twice as far away, then the further star would appear dimmer than the closer star. There are more luminous stars than our Sun but because the Sun is a lot closer, it is brighter. So the brightness of a star depends on it's luminosity and it's distance from the observer. A stars luminosity is a factor of how hot it is, and how big it is.
How many times brighter is a first magnitude star than a third magnitude?
2 magnitudes brighter means it's about 2.512 x 2.512 times brighter. So that's about 6.31 times brighter.
What is brighter a second or a third magnitude star?
2nd magnitude is brighter than 3rd. 6th magnitude is the dimmest that can be seen with the naked eye; many more can be seen in binoculars, telescopes etc.
