X = 1 + root 2 , find the value of (x - 1/x )^3

steposvetlana [31]

Answer:

$(\sqrt{2})^3$

Step-by-step explanation:

Given the expression

$(x - \frac{1}{x} )^3$

Simplify

$(\frac{x^2-x}{x} )^3$

Given that x = 1+√2

Substitute

$(\frac{(1+\sqrt{2} )^2-(1+\sqrt{2} )}{1+\sqrt{2} } )^3\\=( \frac{1+2\sqrt{2} +2 - 1 - \sqrt{2}}{1+\sqrt{2}} )^3\\= (\frac{\sqrt{2}+2}{1+\sqrt{2}})^3 \\Rationalize\\= (\frac{\sqrt{2}-2+2-2\sqrt{2}}{1-2})^3 \\=( \frac{-\sqrt{2}}{-1})^3 \\= (\sqrt{2})^3\\ \\$

Derivative of (a^x/Log a)?

Zolol [24]

<h2> $\large\bold{\underline{\underline{To \: \: Differentive:-}}}$ </h2>

$\sf{\dfrac{a^x}{log(a)} }$

<h3>(OR)</h3>

$\sf{\dfrac{a^x}{ln(a)} }$

<h2> $\large\bold{\underline{\underline{Solution:-}}}$ </h2>

$\sf{Let\ y=\dfrac{a^x}{ln(a)} }$

$\sf{=\dfrac{d}{dx}\bigg[\dfrac{a^x}{ln(a)} \bigg] }$

<h3>(Linear differentiation)</h3>

$\sf{=\dfrac{1}{ln(a)}.\dfrac{d}{dx}(a^x) }$

$\sf{=\dfrac{ln(a)a^x}{ln(a)} }$

$\boxed{\sf{=a^x}}$

<h2> $\large\bold{\underline{\underline{Applied:-}}}$ </h2>

<h3>✭ Linear differentiation</h3>

→ $\sf{[a.b(x)+c.d(x)]'=a.b'(x)+c.d'(x)}$

<h3>✭ Exponential function rule</h3>

→ $\sf{(a^x)'=ln(a).a^x}$
