Question

enter the correct answer in the box. if ( x > 0 ), what is the difference of ( 6xsqrt{14x} - 5sqrt{56x^3} ) in simplest radical form?

Explanation:

Step1: Simplificar el radical segundo

Factorizar el radicando: $5\sqrt{56x^3} = 5\sqrt{4x^2 \cdot 14x}$
Aplicar propiedad de raíces: $5 \cdot \sqrt{4x^2} \cdot \sqrt{14x} = 5 \cdot 2x \cdot \sqrt{14x} = 10x\sqrt{14x}$

Step2: Restar los términos semejantes

Sustituir el término simplificado en la expresión original:
$6x\sqrt{14x} - 10x\sqrt{14x}$
Restar los coeficientes: $(6 - 10)x\sqrt{14x}$

Answer:

$-4x\sqrt{14x}$
