a. M = { 0; 1; 3; 5; 6; 10; 15; 30}

b. P = { 21; 24; 27; 30; 33; 36; 39; 42; 45; 48 }

c. Q = { 0; 7 } 

B; P; L; J F

P L J F G

Lời giải:
$(x-5)^{2018}=(x-5)^{2016}$

$(x-5)^{2018}-(x-5)^{2016}=0$

$(x-5)^{2016}[(x-5)^2-1)=0$

$\Rightarrow (x-5)^{2016}=0$ hoặc $(x-5)^2=1$
$\Rightarrow x-5=0$ hoặc $x-5=1$ hoặc $x-5=-1$

$\Rightarrow x=5$ hoặc $x=6$ hoặc $x=4$

\(\left(x-5\right)^{2016}=\left(x-5\right)^{2018}\)

\(\Leftrightarrow\left(x-5\right)^{2016}-\left(x-5\right)^{2018}=0\)

\(\Leftrightarrow\left(x-5\right)^{2016}\left[1-\left(x-5\right)^2\right]=0\)

\(\Leftrightarrow\left(x-5\right)^{2016}\left(1+x-5\right)\left(1-x+5\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x-5=0\\x-4=0\\6-x=0\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x=5\\x=4\\x=6\end{matrix}\right.\)

`1/5 . (1/2-1/3):(-9/10) + 7/3`

`=1/5 . (3/6-2/6) : (-9/10) + 7/3`

`=1/5 . 1/6 : (-9/10) + 7/3`

`=1/5 . 1/6 xx (-10/9) + 7/3`

`=1/30 xx (-10/9) + 7/3`

`=-1/27 + 7/3`

`=-1/27 + 63/27`

`=62/27`

Lời giải:
$\frac{1}{5}.(\frac{1}{2}-\frac{1}{3}):(\frac{-9}{10})+\frac{7}{3}$

$=\frac{1}{5}.\frac{1}{6}.\frac{10}{-9}+\frac{7}{3}$

$=\frac{1}{30}.\frac{10}{-9}+\frac{7}{3}=\frac{-1}{27}+\frac{63}{27}$

$=\frac{62}{27}$

okkkkkkkkkkkkkkkkkkkkkkkkkkkkk

`-5/8 + 14/8 - 3/8 + 2/9 - 1/2022`

`=-5/8 + 7/4 - 3/8 + 2/9 - 1/2022`

`=(-5/8 -3/8) + 7/4 + 2/9 - 1/2022`

`=-8/8 + 7/4 + 2/9 - 1/2022`

`=-1 + 7/4 + 2/9 - 1/2022`

`=-4/4 + 7/4 + 2/9 - 1/2022`

`=3/4  + 2/9 - 1/2022`

`=35/36 - 1/2022`

`=0.97172766238`

\(\approx0,98\)

Help me

24 và 36

`5x-125=2^3.5^2`

`5x-125=8.25`

`5x-125=200`

`5x=200+125`

`5x=325`

`x=325:5`

`x=65`

Vậy `x=65`
