Question

Evaluate the value of (x

1/x)³ if x = √√2+1. Find the value of x² +1/x².​

Answer 1

Answer:

$\left(\frac{1}{\sqrt{\sqrt{2+1}}}\right)^3=\frac{1}{3^{\frac{3}{4}}}\quad \left(\mathrm{Decimal:\quad }\:0.43869\dots \right)$

Step-by-step explanation:

$\left(\frac{1}{\sqrt{\sqrt{2+1}}}\right)^3$

$\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}$

$=\frac{1^3}{\left(\sqrt{\sqrt{2+1}}\right)^3}$

$1^3=1$

$=\frac{1}{\left(\sqrt{\sqrt{2+1}}\right)^3}$

$\mathrm{Add\:the\:numbers:}\:2+1=3$

$=\frac{1}{\left(\sqrt{\sqrt{3}}\right)^3}$

$=\frac{1}{3^{\frac{3}{4}}}$
