(x-2)3=27
Mà: 33=27
=> (x-2)3=33=27
=> x-2=3
=>x=3+2
=>x=5
( x - 2 )3 = 27
( x - 2 )3 = 33
x - 2 = 3
x = 3 + 2
x = 5
\(\left(x-2\right)^3=27\)
\(\left(x-2\right)^3=3^3\)
\(x-2=3\)
\(\Rightarrow x=3\)
\(\left(x-2\right)^3=27\)
\(\Rightarrow\left(x-2\right)^3=3\)
\(\Rightarrow x-2=3\)
\(\Rightarrow x=5\)
\(\left(x-2\right)^3=27\)
\(\left(x-2\right)=3\)
\(x=3+2\)
\(x=5\)
