Question

Evaluate the expression. \(12+y^{3}\) when \(y=3\)

Short answer

The evaluated expression is 39.

Step-by-step solution

Identify the given variable

Here, the variable in the algebraic expression is \(y\) and it is given that \(y=3\).

Substitute the value into the expression

Replace \(y\) in the expression \(12 + y^3\) by \(3\) to obtain \(12 + 3^3\).

Carry out the operations

First compute the cube of 3 to get \(3^3 = 27\). Then, add this result to 12 to evaluate the entire expression: \(12 + 27 = 39\).
