In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c satisfy the equation a n + b n = c n for any integer value of n greater than 2. 27) On the main sequence, stars obtain their energy A) by converting hydrogen to helium.

During the main sequence star, the outward pressure of heat is counter-acted by the inwardly pressue of gravity which keeps the star at a fairly equilibrium. What keeps it at the equilibrium is the mass and the fuel that it has to burn. The proposition was first stated as a theorem by Pierre de The greater the mass of a main sequence star, the greater its effective temperature.
