Linh Phương you quá nguy hiểm :vvv

3⁶⁰⁰ = 9³⁰⁰

Dó 9³⁰⁰ > 4³⁰⁰ nên 3⁶⁰⁰ > 4³⁰⁰ -_-

y-2x+y-2=8

=>2y-2x=8+2

=>2.(y-x)=10

=>y-x=5

\(x^3+5x^2-6x=0\)

\(x^3-x^2+6x^2-6x=0\)

\(x^2\left(x-1\right)+6x\left(x-1\right)=0\)

\(\left(x-1\right)x\left(x+6\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}x=1\\x=0\\x=-6\end{matrix}\right.\)

\(8^{10}-8^9-8^8=8^8\left(8^2-8-1\right)=8^8.55\) chia hết cho 55.

Vậy \(8^{10}-8^9-8^8\) chia hết cho 55 (đpcm)
