Solve for $x \in R$, $x^9 +x^6 = 36$
Solution
Let, $x^3 =t$
We have, $t^3 +t^2 = 36$
$\therefore t^3 +t^2 -36 = 0$ Continue reading $x^9 +x^6 = 36$
Solve for $x \in R$, $x^9 +x^6 = 36$
Solution
Let, $x^3 =t$
We have, $t^3 +t^2 = 36$
$\therefore t^3 +t^2 -36 = 0$ Continue reading $x^9 +x^6 = 36$
We have, $x^2+1-2x=0$
$\Rightarrow (x-1)^2=0$
$\Rightarrow x=1$
$\therefore x^{99}+\frac {1}{x^{99}}=1+1=2$
$\pi$ and e (the base of the natural logarithm) are two of the most important and widely studied mathematical constants. Although they seem very different from each other, they are actually closely related through various mathematical formulas. Continue reading Relationship Between $\pi$ and e
