Sagot :

¡Claro! Vamos a resolver cada una de las potencias solicitadas paso a paso.

### a. [tex]\(\left(\frac{2}{5}\right)^0\)[/tex]

Cualquier número elevado a la potencia de 0 es igual a 1. Esto se debe a una propiedad fundamental de las potencias.

[tex]\[ \left(\frac{2}{5}\right)^0 = 1 \][/tex]

### b. [tex]\(\left(\frac{-1}{6}\right)^3\)[/tex]

Primero, observamos que estamos elevando una fracción negativa a una potencia impar. Cuando una base negativa se eleva a una potencia impar, el resultado será negativo. Calculamos la potencia:

[tex]\[ \left(\frac{-1}{6}\right)^3 = \frac{(-1)^3}{6^3} = \frac{-1}{216} = -0.0046296296296296285 \][/tex]

### d. [tex]\(0.4^2\)[/tex]

Aquí, simplemente elevamos el número decimal 0.4 al cuadrado. Realizamos los cálculos necesarios:

[tex]\[ 0.4^2 = (0.4) \times (0.4) = 0.16000000000000003 \][/tex]

### e. [tex]\(0.03^2\)[/tex]

De manera similar, elevamos el número decimal 0.03 al cuadrado:

[tex]\[ 0.03^2 = (0.03) \times (0.03) = 0.0009 \][/tex]

### Resumen

[tex]\[ \begin{align*} a. & \left(\frac{2}{5}\right)^0 = 1 \\ b. & \left(\frac{-1}{6}\right)^3 = -0.0046296296296296285 \\ d. & 0.4^2 = 0.16000000000000003 \\ e. & 0.03^2 = 0.0009 \\ \end{align*} \][/tex]

Estos son los valores de cada una de las potencias consultadas.
