Why would a supergiant have a brighter absolute magintude than a white dwarf?

A supergiant is much larger than a white dwarf.
A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.

Which star is cooler and more brighter than the sun?
There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.
How many times brighter is a cepheid variable of absolute magniture -3 than a white dwarf of absolute magnitude of 7?
That is a difference of ten magitudes so the factor in brightness is 10,000.
What kinds of star forms a red giant?
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
What is the color of old stars?
Red (giant, supergiant or dwarf), Blue (supergiant), white (dwarf), blueish white/gamma-ray (neutron star) or produce no light at all (black hole).
Is the sun a red giant or a supergiant?
No. The sun is a G-type main sequence star, sometimes called a yellow dwarf.
Is rigel a dwarf planet or a supergiant?
it is a dwarf planet the size of a supergiant.

Is Betelgeuse a dwarf planet?
Betelgeuse is a supergiant star.
How many times brighter is a cepheid variable of absolute magniture -3 than a white dwarf of absolute magnitude of 7?
That is a difference of ten magitudes so the factor in brightness is 10,000.
What is the absolute value of a white-dwarf?
Depends on the white dwarf in question. They can have a myriad of absolute magnitude values.
Does a red giant or a white dwarf star have greater absolute?
Red giants have typical absolute magnitudes which are 10-15 magnitudes below white dwarfs, which means that the red giants are 10,000-1,000,000 times brighter, after due allowance for distance.
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.
How do you explain what the differences are between main sequence stars white dwarf stars and supergiant stars?
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.
What kind of stars form red giants?
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
