Question

which expression has the greatest value when $x = 3$? $2x^3$ $2x^3 + 5$ $(2x)^3$ $(x - 1)^3$

Explanation:

Step1: Calcular \(2x^3\) cuando \(x = 3\)

Sustituir \(x = 3\) en \(2x^3\): \(2\times(3)^3 = 2\times27 = 54\)

Step2: Calcular \(2x^3 + 5\) cuando \(x = 3\)

Usar el valor de \(2x^3 = 54\) del paso 1, entonces \(54 + 5 = 59\)

Step3: Calcular \((2x)^3\) cuando \(x = 3\)

Sustituir \(x = 3\): \((2\times3)^3 = 6^3 = 216\)

Step4: Calcular \((x - 1)^3\) cuando \(x = 3\)

Sustituir \(x = 3\): \((3 - 1)^3 = 2^3 = 8\)

Answer:

\((2x)^3\) (cuando \(x = 3\), \((2x)^3 = 216\), que es mayor que \(59\), \(54\) y \(8\))
