\(\Leftrightarrow x\cdot\left(x-\sqrt{13}\right)\left(x+\sqrt{13}\right)=0\)
hay \(x\in\left\{0;\sqrt{13};-\sqrt{13}\right\}\)


Pt $\Leftrightarrow (x-4)^3=0\\\Leftrightarrow x-4=0\\\Leftrightarrow x=4$

Giải
32:(x-10)=32.
=>x-10=32:32.
=>x-10=1.
=>x=1+10.
=.x=11.
Vậy x=11

\(\frac{x}{32}=\frac{2}{x}\)
NHÂN CHÉO CHO NHAU TA CÓ:
\(x.x=32.2\)
\(\Leftrightarrow x^2=64\)
\(\Leftrightarrow x^2=8^2\)
\(\Leftrightarrow x=8\)

\(32\left(\frac{1}{8.11}+\frac{1}{11.14}+\frac{1}{14.17}+...+\frac{1}{197.200}\right)-x=\frac{1}{2}\)
\(\frac{32}{3}\left(\frac{3}{8.11}+\frac{3}{11.14}+\frac{3}{14.17}+....+\frac{3}{197.200}\right)-x=\frac{1}{2}\)
\(\frac{32}{3}\left(\frac{1}{8}-\frac{1}{11}+\frac{1}{11}-\frac{1}{14}+\frac{1}{14}-\frac{1}{17}+...+\frac{1}{197}-\frac{1}{200}\right)-x=\frac{1}{2}\)
\(\frac{32}{3}\left(\frac{1}{8}-\frac{1}{200}\right)-x=\frac{1}{2}\)
x=0.78
