Question

Represent the following phrase as an algebraic expression, where "a number" is the letter x. You do not need to simplify. The sum of 4 and the cube of a number.

Answer 1

4+x^3

"The sum of" translates to the addition operation.

"4" is a fixed number, so we represent it as 4.

"the cube of a number" means raising a variable, which is denoted as "a number," to the power of 3. In this case, "a number" is represented by the variable x.
