Answer 2

b: \(\Leftrightarrow x^{10}-x=0\)

\(\Leftrightarrow x\left(x-1\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=1\end{matrix}\right.\)

Answer 3

a)(7X-11³)=2⁵.5²+200

 7x-1331=32.25+200

 7x-1331=800+200

 7x-1331=1000

 7x=1000+1331

 7x=2331

 x=333

b)x¹⁰=x

⇔x10−x=0⇔x10−x=0

$\iff x\left(x-1\right)=0$

⇔[x=0x=1
