100(x-3).(x-2) = 1
=> 100(x-3).(x-2) = 1000
=> (x - 3)(x - 2) = 0
=> x - 3 = 0 => x = 3
hoặc x - 2 = 0 => x = 2
Vậy x = 3; x = 2
tim x biet (x+1)+(x+2)+(x+3)+...+(x+100) =570
tim x biet : (x+1)+(x+2)+(x+3)+...+(x+100)=5550
Tim x biet (x+1)+(x+2)+(x+3)........+(x+100)=5750
tim x biet (x+1)+(x+2)+(x+3)+⋯+(x+100)=5750
tim x biet : ( x + 1 ) + ( x + 2 ) + ( x + 3 ) + ( x + 4 ) + ... + ( x + 100 ) = 5750
bai 5 : tinh
a) tim x , biet (x+1) +(x+2 ) + ...+(x+100)=5750
b) chung minh rang B = 1/2^2 + 1/3^2 + 1/4^2 + ...+1/2021^2 < 1

1.Tim cac chu so x va y de so 1x8y2 chia het cho 36
2.tim cac gia tri nguyen cua n de phan so A=3.n+2/n-1 co gia tri la so nguyen
3.tim cac chu so x y thoa man
(x-2)^2.(x-3)^2=4
4.tim so tu nhien x biet
(x-5):3/100=20.x/100 +5
Tim x ,biet :100:2 nhan {x+1]=25
