i dont understand why

because the x has to satisfy both x>5 and x>2, but since the has to be greater than 2, it can't fall between 5 and 2, because then the equation would be undefined

Think about it this way: The two restrictions must be met. Meaning, the number must be greater than 2 AND it must be greater than 5. But, if it is greater than 2, it is greater than 5! So, the greater than 5 is dominated by the greater than 2 restriction. Therefore the only restriction is greater than 2

but cant there be more than one restriction ? :S

There can. for instance, it it was log(x + 7) + log(x+2), the restrictions would be x + 7 > 0 AND x + 2 > 0 so, it's x< 7 AND x> 2 which reduces to: 2 < x < 7
