3.5 damage calculation question

[Jqspin]

Rolled up a 10th level character. Went fighter2/warblade3/kensai 5

20 Str (+5 mod) using a +2 keen falchion, with leap attack.

Damage would be 2D4+9 + 3X power attack bonus?
On a crit would this do 4d4+18 + 3X power attack?


If I were to throw in the power surge ability and do the same would I get the following calculations?

28 str(+9 mod)

2D4 +13 + 3X power attack
Crit: 4D4 +26 + 3X power attack

Power attack also crits

Yeah, power attack damage would be multiplied too; so on a crit it would be +6x. The rule of thumb is that static bonuses are multiplied, but variable bonuses aren't; so +5 from Power Attack or +2 from being a magic weapon would be multiplied, but (for example) +1d6 from the Flaming enhancement wouldn't be.
