Học tốt nhé!

a. ( 6x - 39 ) : 3 = 201

6x - 39 = 201 . 3

6x - 39 = 603

6x = 603 + 39

6x = 642

x = 642 : 6 

x = 107

b. 23 + 3x = 5⁶ : 5³ 

23 + 3x = 5^{6 - 3}

23 + 3x = 5³ = 125

3x = 125 - 23

3x = 102

x = 102 : 3

x = 34

(6x - 39) : 3 = 201

6x - 39 = 201 x 3 

6x - 39 = 603

6x = 603 + 39

6x = 642

x = 642 : 6

x = 107

23 + 3x = 5⁶ : 5³

23 + 3x = 5^6-3

23 + 3x = 125

3x = 125 - 23

3x = 102

x = 102 : 3 

x = 34

\(\left(6x-39\right):3=201\Rightarrow6x-39=101.3\Rightarrow6x=303+39\Rightarrow x=342:6=57\)

Vậy x = 57

\(23+3x=5^6:5^3\Rightarrow23+3x=125\Rightarrow3x=125-23\Rightarrow x=102:3\Rightarrow x=34\)

Vậy x = 34

k nhaaa

a) [6x - 39 ] : 3 = 201

6x - 39 = 201.3

6x - 39 = 603

6x = 603+ 39

6x = 642

x = 642 : 6

x = 107

Vậy x = 107

b) 23 + 3x = 5^{6 :}  5³

^{23 + 3x  = 125}

3x = 125 - 23

3x = 102

x = 102 : 3

x = 34

Vậy x = 34

Lời giải:
a.

$(x-15).27=0$

$x-15=0:27=0$

$x=15+0=15$

b.

$23(42-x)=0$

$42-x=0$

$x=42$

c.

$(9x+2).3=60$

$9x+2=60:3=20$

$9x=18$

$x=2$
d.

$71+(26-3x):5=75$

$(26-3x):5=75-71=4$

$26-3x=4.5=20$

$3x=26-20=6$

$x=6:2=3$

Sửa:

(6x-39):3=201

6x-39=201.3

6x-39=603

6x=603+39

6x=642

x=107

23+3x=5^6:5^3

23+3x=5^3=125

3x=125-23

3x=102

x=102:3

x=34

a) 6x-39:3=201

6x-13=201

6x=201+13

6x=214

sai đề nha

b) 23+3x=125

3x=125-23

3x=102

x=34

c)tương tự nha

1. a) 6^2 : 4 +2 .5^2= 36 : 4 + 2 . 25 = 9+50=59

b) 2(5.4^2 -18) = 2( 5.16-18) = 2 (80-18) = 2. 62 = 132

2.  a) (6x-39):3 = 201 

=> 6x - 39 = 201 . 3 = 603

=> 6x = 603+39 = 642

=> x = 642 : 6 = 107

b) 23+3x = 5^6:5^3

23+3x = 125

3x = 125-23 =102

x = 102 : 3 =  34
