What is the square root 6n carried to the power of 2/3 in radical form

BaLLatris [955]

Answer: $\sqrt[3]{6n}$

Step-by-step explanation:

We have the following expression:

$(\sqrt{6n})^{\frac{2}{3}}$

Which can be written as follows:

$((6n)^{\frac{1}{2}})^{\frac{2}{3}}$

Multiplying the exponents:

$(6n)^{\frac{1}{3}}$

Writing in radical form we finally have the result:

$\sqrt[3]{6n}$

Does anyone know the answer to this one?

polet [3.4K]

Answer:

$\large\boxed{a(x+4)(x-5)=0,\ a\in\mathbb{R}-\{0\}}\\\\\text{for}\ a=1\to\boxed{x^2-x-20=0}$

Step-by-step explanation:

$\text{If}\ x_1\ \text{and}\ x_2\ \text{are the roots of the quadratic equation}\ ax^2+bx+c=0,\\\text{then}\ ax^2+bx+c=a(x-x_1)(x-x_2).\\\\\text{If}\ x_1\ \text{and}\ x_2\ \text{, then they are the roots of the quadratic equation.}\\\\\text{We have}\ x_1=-4\ \text{and}\ x_2=5.\ \text{Therefore we have the equation:}\\\\a(x-(-4))(x-5)=0\\\\a(x+4)(x-5)=0\qquad\text{for any value of}\ a\ \text{except 0}.$
