Question

( x + 2 )³ = 125

Answer 1

( x + 2 )³ = 125

=> ( x + 2 )³ = 5³

=> x + 2 = 5

     x      = 5 - 2 

     x      = 3

Answer 2

\(\left(x+2\right)^3=125\)

\(\Rightarrow\left(x+2\right)^3=5^3\)

\(\Rightarrow x+2=5\)

\(\Rightarrow x=5-2\)

\(\Rightarrow x=3\)

Answer 3

\(\left(x+2\right)^3=125\)

\(=>\left(x+2\right)^3=\left(5\right)^3\)

\(=>x+2=5\)

\(=>x=5-2\)

\(=>x=3\)
