Question

5x raised to 3+4 x raised to 2 - 6​

Answer 1

`125x^3 + 16x^2 -6`

Explanation:

Given :

5x raised to 3 , that is =

`(5x)^3 = 5^3 * x^3 = 125 x^3`

4x raised to 2 , that is =

`(4x)^2 = 4^2 * x^2 = 16 x^2`

Final step : (5x raised to 3) + ( 4x raised to 2) - 6, that is =

`(5x)^3 +(4x)^2 - 6 \\\\=125x^3 + 16x^2 -6`
