cần câu trả lời cụ thể mà bạn

\(\left(x-2\right)^{x+2}=\left(x-2\right)^{x+1}\)

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

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

\(\left(x-2\right)^{x+1}\left(x-3\right)=0\)

\(\Rightarrow\orbr{\begin{cases}\left(x-2\right)^{x+1}=0\\x-3=0\end{cases}}\)

\(\Rightarrow\orbr{\begin{cases}x-2=0\\x=3\end{cases}}\)

\(\Rightarrow\orbr{\begin{cases}x=2\\x=3\end{cases}}\)

Vậy x = { 2; 3 }

\(\left(x-2\right)^{x+2}=\left(x-2\right)^{x+1}\)

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

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

\(\Rightarrow\hept{\begin{cases}x=2\\x=3\end{cases}}\)

a) Giả sử abcdeg chia hết cho 37                     —> 999abc+(abc+deg) chia hết cho 37

—> 999abc chia hết cho 37  vì 999 :37 ko dư                                                     —>abc + deg  chia hết cho 37

My favourite fictional character would be shinigami ryuk from the anime death note

Reason

Well he is a shinigami who gets bored by his monotonous job of taking souls of humans, so in order to have fun he decides to give his soul reaping powers to a human(light yagami). Through out the whole anime he always sk with the yagami as an ally( although he had made clear to him that he will be having his soul after latter dies) and helps him taking decisions.

Through out the anime, the viewer will never think of him as someone who is in control. He will always be thought of as a insignificant side kick. In the end, he is only one who has the ultimate power and viewer perspective towards him changes from a sidekick to a ringmaster. He takes the soul of yagami when the yagami does not stay true to his word and character.

Through out the series viewer will think that ryuk is an friend to the yagami. It's only in the end when the truth comes out that yagami was nothing more than a tool for ryuk to kill his boredom. Ryuk kills him the very moment he becomes inefficient and untrue to his character.

Ta có công thức 1² + 2³+ 3² + ... + n² = \(\frac{n\left(n+1\right).\left(2n+1\right)}{6}\)

Áp dụng vào công thức ta có:1² + 2³+ 3² + ... + 99² + 100² =\(\frac{100.\left(100+1\right)\left(2.100+1\right)}{6}=\frac{100.101.201}{6}=338350\)

ta có : 4^2x-3 + 7.4^3=4^3.23

           4^2x-3+448    =1472

           4^2x-3            =1024

            4^2x-3           = 4^5 

            2x-3               = 5

            2x                  = 8 

            x                     =4

đúng thì mình 1 cái
