\(7^x-7^{x+2}=-2352=7^x-7^x.7^2\Rightarrow7^x-7^x.49=-2352\Rightarrow7^x.-48=-2352\)

\(\Rightarrow7^x=-2352:-48=49=7^2\Rightarrow x=2\)

\(7^x-7^{x+2}=-2352\)

\(7^x\left(1-49\right)=-2352\)

\(7^x.\left(-48\right)=-2352\)

\(\Rightarrow7^x=49\Leftrightarrow x=2\)

\(7^x-7^{x+2}=-2352\)

\(\Rightarrow7^x-7^x.7^2=-2352\)

\(\Rightarrow7^x.\left(1-49\right)=-2352\)

\(\Rightarrow7^x.\left(-48\right)=-2352\)

\(\Rightarrow7^x=49=7^2\)

\(\Rightarrow x=2\)

Vậy \(x=2\)

Theo đầu bài , x = 2350

vô tận

tân cùng là 2 nhé

Ta có : 84= 2352 : 28 

=> de 2352 : x > 84

<=> 2352 : x > 2352 : 28 

=> x < 28

=> x=26 hoac x = 27

ủa từ de là từ gì

\(173\times\left(x:1792\right)=0\)

\(\Rightarrow x:1792=0:173\)

\(\Rightarrow x:1792=0\)

\(\Rightarrow x=0\times1792\)

\(\Rightarrow x=0\)

Vậy x = 0

_Chúc bạn học tốt_

suy ra x.1792=0

suy ra x=0

Có 1 TH duy nhất  là x : 1792 = 0

                                  x             = 0. 1792

                                   x            = 0

                        ==> x=0

thiếu đề bài rùi bạn ơi

48 * 49 = 2352

48. 49 = 2352

2352 * 1 = 2352

`@` `\text {Ans}`

`\downarrow`

\(1793\cdot\left(x\div1792\right)=0\)

`\Rightarrow x \div 1792 = 0 \div 1793`

`\Rightarrow x \div 1792 = 0`

`\Rightarrow x = 0. 1792`

`\Rightarrow x = 0`

Vậy, `x = 0.`

\(1793.\left(x:1792\right)=0\)

\(=>x:1792=0:1793\)

\(=>x:1792=0\)

\(=>x=0.1792\)

\(=>x=0\)

$@$ $\text{Ans}$

$\downarrow$

$1793\cdot \left(x÷1792\right)=0$

$\Rightarrow x÷1792=0÷1793$

$\Rightarrow x÷1792=0$

$\Rightarrow x=0.1792$

$\Rightarrow x=0$

Vậy, $x=0.$
