What is the following sum? 5(^3sqaure root x)+9(^3sqaure root 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)

 14 (3 sqrt x)

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
