Empower Spell + Sneak Attack Dice

[GM PDK]

If an arcane trickster is invisible and has 3d6 sneak attack dice, and cast an empowered ray of frost, is the damage:

A) (1d3*1.5) + 3d6; or
B) (1d3+3d6)*1.5.

Thank you!

Considering "http://paizo.com/threads/rzs2u9p0?Empowered-Spell-and-Sneak-Attack", the consensus would be A.

PS: Deleted my first answer, misread the question.

[Syries]

Sneak attack is extra dice that is added to the normal damage dealt after all other calculations are made, so the answer would be A, not B

[GM PDK]

The Empower Spell feat wording of 'including bonuses to those dice rolls' has me slightly hesitant though...

[dragonhunterq]

Sneak attack isn't a bonus to a roll - it is additional damage dice.
Bonuses to the dice rolls would be something like a sorceror bloodline power that add +1 to each damage dice, or the +level added to d8s in cure spells.
