b ) 3^x-1 =27
c) (x-1) ^3 = 4(x-1)
d) 5^x 5^x-2= 130
ai giup mk nhanh nhat mk se tick cho 4 lan luon
a , 3x - 4 = 57 : 56
3x - 4 = 57-6
3x -4 = 5
3x = 9
3x = 32
suy ra x = 2
Vậy x =2
b , 3x-1 = 27
3x-1 = 33
suy ra x - 1 =3 suy ra x = 3-1 =2
Vậy x =2
c , (x-1)3 = 4(x-1)
( x - 1)3 : ( x-1 ) = 4
(x-1)3-1 = 4
(x-1)2 = 22
suy ra x-1 =2 suy ra x = 2+1 =3
Vậy x =3
d , 5x . 5x-2 = 130
5x . 5x : 52 = 130
52x = 130 x 25
52s = 3250
suy ra x thuộc rỗng
Vậy x thuộc rỗng
a) 3^x -4 =5^7 : 5^6
3^x -4 =5
3^x=9
x=2
b ) 3^x-1=26
3^x=27
x=3
\(3^x-4=5^7:5^6\)
\(3^x-4=5\)
\(3^x=5+4\)
\(3^x=9\)
\(\Rightarrow x=2\)
\(3^x-1=26\)
\(3^x=26+1\)
\(3^x=27\)
\(\Rightarrow x=3\)

Ban nao tra loi nhanh nhat minh se tick dung!

Thank!!!!!!!!!!!!!!!!!!!!!!!
Ban Le Tue Chi oi, cach giai nhu the nao?
Tim x, biet
x=2.2.2.2.2-21-3-4-5+343243
Viet co loi giai minh se tick
x = 2.2.2.2.2 - 21 - 3 - 4 - 5 + 343243
x = 32 - 21 - 3 - 4 - 5 + 343243
x = 343243 - 1
x = 343242
Vậy x = 343242
Bai 1 : Tim x :
a ) 1/2 . ( x - 1 ) + 1/3 . ( 1. x ) =2
b ) 1/2 . x - 1/2 + 1/3 . x
c ) 1/2 . ( x -1 ) + 1/3 = -1/2 .x
d ) 3/7 . ( 1 - x ) - 1/5 = 1/7 .x
e ) 1/2 . ( x -1 ) = 1/3 . ( x-2 )
Ai lam nhanh va dung mk se tick cho nha .
