=> (x-1)^5 = (-3)^5
=> x-1 = -3
=> x = -2
(x-1)^5=-243
(x-1)^5=(-3)^5
x-1 =-3
x =(-3)+1
x = -2
\(\left(x-1\right)^5=-243\)
\(\left(x-1\right)^5=-243\)
\(\left(x-1\right)^5=\left(-3\right)^5\)
\(x-1=-3\)
\(x=-3+1\)
\(x=-2\)
(x-1)^5=-243
=>(x-1)^5=(-3)^5
=>x-1=-3
=>x=-3+1
=>x=-2
(x - 1)5 = -243
=> (x - 1)5 = (-3)5
=> x - 1 = -3
=> x = -3 + 1
=> x = -2
Vậy x = -2
\(\left(x-1\right)^5=-243\)
\(\Rightarrow\left(x-1\right)^5=\left(-3\right)^5\)
\(\Rightarrow x-1=-3\)
\(\Rightarrow x=-2\)
(x-1)^5 = -243
=>(x-1)5=(-3)5
=>x-1=-3
=>x=2
