what is the value of 2(0.5)^2?
Step1: Analizar la función exponencial
Tenemos la función \( y = 2(0.5)^x \) y queremos encontrar el valor cuando \( x = 2 \), es decir, calcular \( 2(0.5)^2 \).
Step2: Calcular la potencia
Primero, calculamos \( (0.5)^2 \). Sabemos que \( 0.5=\frac{1}{2} \), entonces \( (\frac{1}{2})^2=\frac{1}{2}\times\frac{1}{2}=\frac{1}{4} = 0.25 \).
Step3: Multiplicar por el coeficiente
Ahora, multiplicamos este resultado por 2: \( 2\times0.25 = 0.5 \).
