i don't understand what "3 ^4√3" means

anonymous · Answer

it means that the 4 is on top of that triangle part of the radical sign

anonymous · Answer

$$3\sqrt[4]{3}-8\sqrt[3]{3}+5\sqrt[4]{3}+4\sqrt[3]{3}$$

anonymous · Answer

combine like terms, like in 
$$3x-8y+5x+4y$$

anonymous · Answer

you get 
$$8\sqrt[4]{3}-4\sqrt[3]{3}$$
