\(\left(15x-3\right)^{2019}=1=1^{2019}\)
\(\Rightarrow15x-3=1\)
\(\Rightarrow15x=3\)
\(\Rightarrow x=\frac{3}{15}\)
\(\Rightarrow x=\frac{1}{5}\)
=>(15x-3)2019=12019
=>15X-3=1
=>15X=4
=>X=4/15
GIÚP MK LÊN 333 SP NHÉ
\(\left(15x-3\right)^{2019}=1\)
\(\Leftrightarrow\left(15x-3\right)^{2019}=1^{2019}\)
\(\Leftrightarrow15x-3=1\)
\(\Leftrightarrow15x=4\)
\(\Leftrightarrow x=\frac{4}{15}\)
P/s tham khảo nhaaaa
Bài làm
( 15x - 3 )2019 = 1
=> ( 15x - 3 )2019 = 12019
=> 15x - 3 = 1
=> 15x = 4
=> x = \(\frac{4}{15}\)
Vậy x = \(\frac{4}{15}\)
# Học tốt #
(15x-3)2019=1
(15x-3)2019=12019
Suy ra:15x-3=1
15x=4
x=3,75
15x-3=1/2019
15x=6058/2019
x=6058/10095
(15x-3)^2019=1
(15x-3)^2019=1^2019
=>15x-3=1
15x =1+3
15x = 4
=> x =4:15
x =4/15
Vậy x=4/15
