Question

(x^5)^2=x^18/x^7

Answer 1

\(\left(x^5\right)^2=\dfrac{x^{18}}{x^7}\left(đk:x\ne0\right)\)

\(\Rightarrow x^{10}=x^{11}\)

\(\Rightarrow x^{11}-x^{10}=0\)

\(\Rightarrow x^{10}\left(x-1\right)=0\)

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