\(\left(2x+1\right)^5=\left(2x+1\right)^{2010}\)

\(\Rightarrow\left(2x+1\right)^{2010}-\left(2x+1\right)^5=0\)

\(\Rightarrow\left(2x+1\right)^5.\left[\left(2x+1\right)^{2005}-1\right]=0\)

\(\Rightarrow\orbr{\begin{cases}\left(2x+1\right)^5=0\\\left(2x+1\right)^{2005}-1=0\end{cases}}\)\(\Rightarrow\orbr{\begin{cases}2x+1=0\\\left(2x+1\right)^{2005}=1\end{cases}}\)\(\Rightarrow\orbr{\begin{cases}2x+1=0\\2x+1=1\end{cases}}\)\(\Rightarrow\orbr{\begin{cases}2x=-1\\2x=0\end{cases}}\)

\(\Rightarrow\orbr{\begin{cases}x=-\frac{1}{2}\\x=0\end{cases}}\)

Vậy \(\orbr{\begin{cases}x=-\frac{1}{2}\\x=0\end{cases}}\)

(2x+1)⁵=(2x+1)²⁰¹⁰

=> 2x+1=1 hoặc 2x+1=0

=>2x=0  hoặc 2x=1

=>x=0 hoặcx=0,5

(2x+1)^5=(2x+1)^2010 =>(2x+1)^2010 - (2x+1)^5=0

                                  =>(2x+1)^5 * ((2x+1)^2010-1) = 0

                                 =>2x+1=0 hoặc 2x+1=1

                                 =>x=-1/2 hoặc x=0 

vậy x=-1/2 hoặc x=0

\(\left(2x+1\right)^3=-0,001\)

\(\Rightarrow\left(2x+1\right)^3=\left(-0,1\right)^3\)

\(\Rightarrow2x+1=-0,1\)

\(\Rightarrow2x=-\frac{1}{10}-1\)

\(\Rightarrow2x=-\frac{11}{10}\)

\(\Rightarrow x=-\frac{11}{10}:2\)

\(\Rightarrow x=-\frac{11}{10}.\frac{1}{2}=-\frac{11}{20}\)

-11/20

giống cái kia thôi bn

Mik làm rồi mà

Mà cái bn Nguyễn Duy Đạt gì đó làm thiếu 1 trường hợp

Mà bn vẫn kik hở

Sao zzzzz??????

chắc nhầm ! Xin lỗi ! Xin lỗi !

\(\left(2x-1\right)^6=\left(2x-1\right)^8\Leftrightarrow\left(2x-1\right)^6-\left(2x-1\right)^8=0\)

\(\Leftrightarrow\left[\left(2x-1\right)-\left(2x-1\right)\right]...=0\Leftrightarrow x=0\)

''...'' vế sau á :), ko chắc 

a/ \(\left|1-2x\right|>7\Leftrightarrow\left[{}\begin{matrix}1-2x=7\\1-2x=-7\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}2x< -6\\2x< 8\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x< -3\\x< 4\end{matrix}\right.\)

b/ \(\dfrac{-5}{x-3}< 0\Leftrightarrow x-3>0\) ( vì -5<0)

\(\Leftrightarrow x>3\)

sao ko trả lời câu c

.............................................................................................................................................................................................????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????.....................................................................................................................................................................?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

a)

\(\int\frac{2\left(x_{ }+1\right)}{x^2+2x_{ }-3}dx=\int\frac{2x+2}{x^2+2x-3}dx\)

\(=\int\frac{d\left(x^2+2x-3\right)}{x^2+2x-3}=ln\left|x^2+2x-3\right|+C\)

b)\(\int\frac{2\left(x-2\right)dx}{x^2-4x+3}=\int\frac{2x-4dx}{x^2-4x+3}=\int\frac{d\left(x^2-4x+3\right)}{x^2-4x+3}=ln\left|x^2-4x+3\right|+C\)

Bài 2: 

a: Ta có: \(2^{x+1}\cdot3^y=12^x\)

\(\Leftrightarrow2^{x+1}\cdot3^y=2^{2x}\cdot3^x\)

\(\Leftrightarrow\left\{{}\begin{matrix}x+1=2x\\x=y\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x=1\\y=1\end{matrix}\right.\)
