Question

¿qué expresión tiene el mayor valor cuando x = 3?
2x³
2x³ + 5
(2x)³
(x − 1)³

Explanation:

Step1: Calculate \(2x^3\) when \(x = 3\)

Substitute \(x = 3\) into \(2x^3\), we get \(2\times3^3=2\times27 = 54\).

Step2: Calculate \(2x^3 + 5\) when \(x = 3\)

Substitute \(x = 3\) into \(2x^3+5\), we get \(2\times3^3 + 5=54 + 5 = 59\).

Step3: Calculate \((2x)^3\) when \(x = 3\)

Substitute \(x = 3\) into \((2x)^3\), we get \((2\times3)^3=6^3 = 216\).

Step4: Calculate \((x - 1)^3\) when \(x = 3\)

Substitute \(x = 3\) into \((x - 1)^3\), we get \((3 - 1)^3=2^3 = 8\).

Answer:

\((2x)^3\)
