Simplify:
5(cube root of 16) + 2(cube root of 54)
5 times the cube root of 16 plus 2 times the cube root of 54.
I do not know how to type in the radical signs. Sorry.

Algebra 
Steve,
5∛16 + 2∛54
Try to find perfect cubes under the ∛
5∛(8*2) + 2∛(27*2)
5(∛8∛2) + 2(∛27∛2)
5(2∛2) + 2(3∛2)
10∛2 + 6∛2
16∛2
