it is stated that the minimum to destroy a planet is 10.000 of power level, which raditz doesn't have as his power level is 1.500
COMPLETELY not what that says, it just says a power level of 10k CAN destroy a planet, it never says "if the minimum to destroy a planet"
It just says 10k is a confortable value to destroy a planet. They're not gonna say "Oh, a 950 can destroy a planet, so then 150,000,000 is 157894.736842x stronger!!!"
the point is to show there are a lot more zeros, that's about it.
"Si con una fuerza de combate de 10.000 se puede destruir un planeta"
if it was
actually saying what you claim, they would've said:
"si la fuerza de combate minima para destruir in planeta es 10,000, imaginate que puede hacer..."
"if the minimum power level to destroy a planet is 10,000, imagine what..."
However, the lowest attack we know that can one shot a planet is the Galick Gun, from Vegeta. And if you want to use the statement from El Manga Legendario that a PL of at least 10k can do it, that's another thing pointing at the fact, Raditz himself couldn't do it alone, since he's way below that PL.
Saying it's the minimum power to destroy a planet is also unfounded, based on the fact that this is just DC. It could have the overall joules, and just not the DC.
Say, a low 5-B attack would effectively send a planet asunder too, even being conservative for Vegeta's normal power, showing that the galick Gun is specifically special in its DC.
