\(\left(2x+1\right)^3=125\)
\(\Rightarrow\left(2x+1\right)^3=5^3\)
\(\Rightarrow2x+1=5\)
\(\Rightarrow x=2\)
Vậy x = 2
\(\left(2x+1\right)^3=125\)
\(\Rightarrow\left(2x+1\right)^3=5^3\)
\(\Rightarrow2x+1=5\)
\(\Rightarrow2x=4\)
\(\Rightarrow x=2\)
Vậy \(x=2\)
(2x+1)3= 125
(2x+1)3=53
\(\Rightarrow\) 2x+1=5
2x = 5-1
2x =4
x = 2
(2x + 1)3 = 125
(2x+1)3=53
2x+1=5
2x=5-1
2x=4
x=4/2
x=2
(2x+1)^3=5^3
2x+1=5
2x=5-1
2x=4
x=4:2
x=2
