How did mew vmax do 340 damage to my galarian slowking vmax?

They had a mew v with 2 fusion strike energy, two genesect v and a meloetta fusion strike. I was expecting to do 280 from the meloetta, hoping to survive the attack and play on. Instead it did 340, knocked me out and he took the game...

Ps can meloetta do more than 280 (70x4)?

There's an item almost all Mew lists play 4 copies of which is Power Tablet, which increases the damage your Fusion Strike Pokemon deals to the opposing active Pokemon by 30, you only need to use 2 to reach from 280 to 340.
