Question

evaluate the expression. x = 5 y = 2 4x + y^3

Explanation:

Step1: Substitute x and y values

Substitute \(x = 5\) and \(y = 2\) into \(4x + y^{3}\). So we get \(4\times5+2^{3}\).

Step2: Calculate multi - plication and exponentiation

First, calculate \(4\times5 = 20\) and \(2^{3}=2\times2\times2 = 8\). We now have \(20 + 8\).

Step3: Calculate the sum

\(20+8=28\).

Answer:

28
