Question

(x-1)^5 = -243

Answer 1

=>  (x-1)^5 = (-3)^5

=>  x-1 = -3

=>  x = -2

Answer 2

(x-1)^5=-243

(x-1)^5=(-3)^5

x-1    =-3

  x    =(-3)+1

  x    = -2

Answer 3

\(\left(x-1\right)^5=-243\)

\(\left(x-1\right)^5=-243\)

\(\left(x-1\right)^5=\left(-3\right)^5\)

\(x-1=-3\)

\(x=-3+1\)

\(x=-2\)

Answer 4

(x-1)^5=-243

=>(x-1)^5=(-3)^5

=>x-1=-3

=>x=-3+1

=>x=-2

Answer 5

(x - 1)⁵ = -243

=> (x - 1)⁵ = (-3)⁵

=> x - 1 = -3

=> x = -3 + 1 

=> x = -2

Vậy x = -2

Answer 6

\(\left(x-1\right)^5=-243\)

\(\Rightarrow\left(x-1\right)^5=\left(-3\right)^5\)

\(\Rightarrow x-1=-3\)

\(\Rightarrow x=-2\)

Answer 7

(x-1)^5 = -243

=>(x-1)⁵=(-3)⁵

=>x-1=-3

=>x=2
