add 9 to 10, multiply n by the result, then raise what you have to the 3rd power

Question

It has to be in an algebraic expression.

Answer 1

((9+10)n)^3

Add 9 to 10:

9+10=19

Multiply n by the result:

19*n=19n

Raise what you have to the 3rd power:

(19n)^3 = 6859n^3

((9+10)n)^3 = 6859n^3

Answer 2

[(9+10)*n]^3 = (19n)^3 = 19^3*n^3 = 6859n^3
