Question

\(4x^3\)+15 =47

 

Answer 1

\(4x^3+15=47\)

\(4x^3=47-15\)

\(4x^3=32\)

\(x^3=32\div4\)

\(x^3=8\)

\(x^3=2^3\)

\(\Rightarrow x=2\)

Answer 2

4x³ + 15 =47

4 x ³      = 47 - 15

4 x ³      =32

x ³             =32 : 4

x ³        = 8

x ³       = 2 ³

=> x = 2

Answer 3

\(4x^3+15=47\)

\(4x^3=47-15\)

\(4x^3=32\)

\(x^3=32:4\)

\(x^3=8\)

\(x^3=2^3\)

\(=>x=3\)

Answer 4

\(4x^3+15=47\)

\(4x^3=47-15\)

\(4x^3=32\)

\(x^3=32:4\)

\(x^3=8\)
