Question

(x-5)^3=-64

Answer 1

\(\Leftrightarrow x-5=-4\)

\(\Leftrightarrow x=-4+5=1\)

Vậy ...

Answer 2

(x - 5)³ = - 64

\(\Rightarrow\) (x - 5)³ = - 64 = (- 4)³

\(\Rightarrow\) x - 5 = - 4

\(\Rightarrow\) x = 1

Vậy x = 1

Answer 3

(x - 5)³ = -64

=> x - 5³ = -64

=> x - 125 = -64

=> x = -64 + 125

=> x = 61
