tolong jawab yg benar....pake cara nya

2017 ×(2016^2 -16)×2015 / 2020×(2016^2-1)

= 2017 ×(2016^2 - 4^2)×2015 / 2020×(2016^2-1^2)

= (2017 × (2016-4) ×(2016+4) ×2015) / (2020 ×(2016+1) ×(2016-1))

= (2017 × 2012 × 2020 × 2015) / (2020 × 2017 × 2015)

= (2017/2017) × 2012 × (2020/2020) × (2015/2015)

= 1 × 2012 × 1 × 1

= 2012
