cho S=1 + 2018 + 20182 +20183 + 20184 + 20185+ 20186 + 20187
a=\(\frac{-7}{2018^{2019}}\)+ \(\frac{-15}{2018^{2018}}\)
b= \(\frac{-15}{2018^{2019}}\)+ \(\frac{-7}{2018^{2018}}\)
mk cần gấp nha
Tinh:A=2010^2010.(7^10:7^8-3.2^4-2^2018:2^2018)
Gấp lắm bạn !!!?!!!!
a. A=(157×2018-99×2018-2018) : 2018-57
b. B=(1+3+5+7+...+2018) × (135135×137-135×137
a) (-45) + (-2018) + /-145/ + /-2018/
b) 5^3 . 4^2 + 85 . 5^3 - 5^7 : 5^4
c) (7^108 . 50 - 7^108) : 7^110
a,Tìm các cặp số nguyên x,y thỏa mãn:
5+x/7+x=5/7 và x+y=24
b,So sánh : A=2017^2017+1/2018^2018+1 và B+2018^2018+1/2019^2019+1
2018*x(x-2018/7)=0
A,(6 mũ 2019 - 6 mũ 2018) : 6 mũ 2018
B, ( 7 mũ 2020 + 7mũ 2019): 7 mũ 2019
Cho A = 2018 + 20182 + 20183 +...+ 201812
B = 201810 + 20187 + 20184 + 2018
Chứng minh rằng A \(⋮\)B
\(\frac{-21+\frac{7}{17}-\frac{7}{29}+\frac{7}{2018}}{27-\frac{9}{17}+\frac{9}{29}-\frac{9}{2018}}-\frac{2}{9}\)
