a) Ta có I 2x - 1 I = 2015

=> 2x-1=2015 hoặc 2x-1=2015

+,Th1: 2x-1=2015

             2x=2015+1

             2x=2016

              x=2016:2

             x=1008

+,Th2: 2x-1=-2015

              2x=-2015+1

             2x=-2014

              x=-2014:2

             x=-1007

Vậy x=1008, x=-1007

 

 

|x-1|<5

th1: x-1<5=> x<6

th2: x-1<-5=> x<-4

vậy x <6 hoặc<-4

|x-1|>5 cũng tương tự như thế

còn mấy câu khác Nguyễn Diệu Thảo làm thế chắc bạn cũng biết cách làm rồi

|7 + 5x| = 1 - 4x

=> \(\orbr{\begin{cases}7+5x=1-4x\left(đk:x\le\frac{1}{4}\right)\\7+5x=4x-1\left(đk:x\ge\frac{1}{4}\right)\end{cases}}\)

=> \(\orbr{\begin{cases}7-1=-4x-5x\\7+1=4x-5x\end{cases}}\)

=> \(\orbr{\begin{cases}6=-9x\\8=-x\end{cases}}\)

=> \(\orbr{\begin{cases}x=-\frac{2}{3}\left(tm\right)\\x=-8\left(ktm\right)\end{cases}}\)

|4x- 2x| + 1 = 2x

=> |4x2 - 2x| = 2x - 1

#It's the moment when you're in good mood, you accidentally click back =.=

1) Calculate

\(P=1\frac{1}{3}.1\frac{1}{8}.1\frac{1}{15}....1\frac{1}{63}.1\frac{1}{80}\)

\(=\frac{4}{3}.\frac{9}{8}.\frac{16}{15}....\frac{64}{63}.\frac{81}{80}\)

\(=\frac{2.2}{1.3}.\frac{3.3}{2.4}.\frac{4.4}{3.5}....\frac{8.8}{7.9}.\frac{9.9}{8.10}\)

\(=\frac{2.9}{10}=\frac{9}{5}\)

ta có: 10010 + 1 > 10010 - 1

⇒ A = \(\frac{100^{10}+1}{100^{10}-1}< \frac{100^{10}+1-2}{100^{10}-1-2}=\frac{100^{10}-1}{100^{10}-3}=B\)

vậy A < B

a) |2x +1| = 7

Th1: 2x + 1 = 7 

<=> x  = 3

Th2: 2x + 1 = -7 

<=> x = -4

\(1)\) Ta có : 

\(\left|2x-1\right|\ge0\)

\(\Leftrightarrow\)\(A=\left|2x-1\right|+8\ge8\)

Dấu "=" xảy ra \(\Leftrightarrow\)\(\left|2x-1\right|=0\)

\(\Leftrightarrow\)\(2x-1=0\)

\(\Leftrightarrow\)\(2x=1\)

\(\Leftrightarrow\)\(x=\frac{1}{2}\)

Vậy GTNN của \(A\) là \(8\) khi \(x=\frac{1}{2}\)

\(2)\) Ta có : 

\(B=\left|x-3\right|+\left|x-9\right|-1\)

\(B=\left|x-3\right|+\left|9-x\right|-1\ge\left|x-3+9-x\right|-1=\left|6\right|-1=6-1=5\)

Dấu "=" xảy ra khi và chỉ khi \(\left(x-3\right)\left(9-x\right)\ge0\)

Trường hợp 1 : 

\(\hept{\begin{cases}x-3\ge0\\9-x\ge0\end{cases}\Leftrightarrow\hept{\begin{cases}x\ge3\\x\le9\end{cases}\Leftrightarrow}3\le x\le9}\)

Trường hợp 2 : 

\(\hept{\begin{cases}x-3\le0\\9-x\le0\end{cases}\Leftrightarrow\hept{\begin{cases}x\le3\\x\ge9\end{cases}}}\) ( loại ) 

Vậy GTNN của \(B\) là \(5\) khi \(3\le x\le9\)
