( 2016 * 2017 + 2018 * 2 + 2015 ) : [ ( 2018 : 2017 - 2017 * 2015 ) + 2016 ]

2018 * 20182017 - 2017 * 20172018

2018 * 20182017 - 2017 * 20182018

Bai nay la bai tinh nhanh nha

Tính:

A=2019/2018 - 2018/2017 + 2017/2016 - 2016/2015

B=1/2019 - 1/2018 + 1/2017 - 1/2016

C=1/2017 - 1/2016 + 1/2015 - 1/2014

tính nhanh a=(2017+2016*2018)/(2016*2017+4033)

t5inh nhanh phan so ;2016/2017+2017/2018+2018/2016=

tính nhanh:

a) (2016*2017+2018*2+2015):[(2018*2017-2017*2015)+2016]

b)2018*20182017-2017*20182018

c)1+2-3-4+5+6-7-8+...+298-299-300+301+302

( 2016 x 2017 + 2018 x 2 + 2015 ) : [ ( 2018 : 2017 - 2017 x 2015 ) + 2016 ]

Tính nhanh nhé!

tính nhanh a=2017+2016*2018/2016*2017+4033

ai nhanh đúng mình tick cho .

Tính :A= [(2018/1)+(2017/2)+(2016/3)+(2015/4)+...+(4/2015)+(3/2016)+(2/2017)+(1/2018)]/[(2019/1)+(2019/2)+(2019/3)+(2019/4)+...+(2019/2015)+(2019/2016)+(2019/2017)+(2019/2018)+(2019/2019)]

Tính :A= [(2018/1)+(2017/2)+(2016/3)+(2015/4)+...+(4/2015)+(3/2016)+(2/2017)+(1/2018)]/[(2019/2)+(2019/3)+(2019/4)+(2019/5)+...+(2019/2015)+(2019/2016)+(2019/2017)+(2019/2018)+(2019/2019)]

Tính nhanh:

\(\frac{2016×2018+2}{2016×2017+2018}\)
