2

Answer 2

Mik cần lời giải chi tiết nha

Answer 3

( x + 2 )³ = 41 + 23

( x + 2 )^{3 =} 64

( x + 2 )^{3 =} 4³

=> x + 2 = 4

x = 4 - 2

x = 2

Answer 4

\(\left(2+x\right)^3-23=41\)

\(\Rightarrow\left(2+x\right)^3=64\)

\(\Rightarrow\left(2+x\right)^3=4^3\)

\(\Rightarrow2+x=4\)

\(\Rightarrow x=2\)

Answer 5

\(\left(2+x\right)^3-23=41\)

\(\left(2+x\right)^3=41+23\)

\(\left(2+x\right)^3=64\)

\(\left(2+x\right)^3=4^3\)

\(2+x=4\)

\(x=4-2\)

\(x=2\)
