Question

Which of these algebraic expressions matches the verbal description "k cubed plus 7"? a. k3 +7 b. (k + 7) C. k + 73 d. 3k + 7 e 30k + 7)​

Answer 1

A

Explanation:

Just as squared has an exponent of 2, cubed has an exponent of 3.

Therefore, k is seen as
`K^(3)` (or K^3 if that is too small to see)

Another keyword is "plus" as this indicates addition which has a symbol of +

So in this case, your answer would be A) K^3 + 7
