Multiply and simplify. All variables represent positive real numbers. ☺️

Question

[(³√2t)+(³√5t)] [(³√3t)+(2 ³√4t)]

Answer 1

Multiply applying the FOIL method.

 

³√(6t²) + ³√(8t²) + ³√(15t²) + 2 ³√(20t²) =

 

³√(6t²) + 2  ³√(t²) + ³√(15t²) + 2 ³√(20t²)

 

 

That is all you can do, since 6, 15, and 20 are not perfect cubes and their prime factorization cannot be combined.
