when $$\sqrt[4]{2^7\cdot3^3}$$is fully simplified, the result is $$a\sqrt[4]{b}$$, where a and b are positive integers. what is a + b ?

i think my main problem is that when i simplify that first expression, i don't get what i'm supposed to, i just get a big number.

( 27 · 33 )1/4  =  ( 24 · 23 · 33 )1/4  =  ( 24 )1/4 · ( 23 · 33 )1/4  =  2 · ( 216 )1/4

2 $$\sqrt[4]{}$$(23  * 33 )

2 $$\sqrt[4]{}$$(216)
