Ta có:\(\left(x-2\right)^5=243=3^5\Rightarrow x-2=3\Rightarrow x=5\)
Vậy x=5
Ta có: x − 2 5 = 243 = 3 5 ⇒x − 2 = 3⇒x = 5
Vậy x = 5
k cho mk nha ^_^
(x-2)^5=243 .
(x-2)^5=3^5 .
x-2=5 .
x=5-2 .
x=3 .
(x-2)^5=243 .
(x-2)^5=3^5 .
x-2=3 .
x=3+2 .
x=5 .
(x-2)^5=243 .
(x-2)^5=3^5 .
x-2=3 .
x=3+2 .
x=5 .
(x-2)^5=243 .
(x-2)^5=3^5 .
x-2=3 .
x=3+2 .
x=5 .
\(\left(x-2\right)^5=243\)
\(\left(x-2\right)^5=3^5\)
\(\Rightarrow x-2=3\)
\(\Rightarrow x=5\)
vậy \(x=5\)
