Respuesta :

5(3√x) +9(3√x)  = 15√x+27√x= 42√x

5∛x + 9∛x = 14∛x
For this case we have the following expression:
 5 (3sqrt x) +9 (3 sqrt x)
 We can do common factor of the term that is repeated in both parts of the expression.
 The term that is repeated is:
 (3 sqrt x)
 Rewriting we have:
 (3 sqrt x) * (5 + 9)
 (3 sqrt x) * (14)
 14 (3 sqrt x)
 Answer:
 
14 (3 sqrt x)
