Question

x⁵=x³ nhanh giúp ạ

 

Answer 1

\(x^5-x^3=0\\ x^3\left(x^2-1\right)=0\\ \left[{}\begin{matrix}x^3=0\\x^2-1=0\end{matrix}\right.=>x=0;x=1;x=-1\)

Answer 2

=>x³(x²-1)=0

=>x(x-1)(x+1)=0

hay \(x\in\left\{1;-1;0\right\}\)

Answer 3

Đáp án :  \(x=0\) hoặc \(x=\pm1\).

Answer 4

3⁵=5³

100/100 đúng

Answer 5

`x^5 - x^3 = 0`

`x^3(x-1)(x+1)  =0`

`=> x = 0` hoặc `+-1`
