Answer:
[tex]125x^3 + 16x^2 -6[/tex]
Step-by-step explanation:
Given :
5x raised to 3 , that is =
[tex](5x)^3 = 5^3 \times x^3 = 125 x^3[/tex]
4x raised to 2 , that is =
[tex](4x)^2 = 4^2 \times x^2 = 16 x^2[/tex]
Final step : (5x raised to 3) + ( 4x raised to 2) - 6, that is =
[tex](5x)^3 +(4x)^2 - 6 \\\\=125x^3 + 16x^2 -6[/tex]
