Question

`5{x}^(4)(4 {x}^(5) + 3 {x}^(2) - 8)`
​

Answer 1

The answer would be 20x^9 + 15x^6 - 40x^4

Answer 2

`5x^4\left(4x^5+3x^2-8\right)`

`5x^4\left(4x^5+3x^2-8\right)=5x^4\cdot \:4x^5+5x^4\cdot \:3x^2+5x^4\left(-8\right)`

`=5x^4\cdot \:4x^5+5x^4\cdot \:3x^2+5x^4\left(-8\right)`

`=20x^9+15x^6-40x^4`
