hay giup toi giai toan bai tim x
(4x+3) chia het (x-2)
giai giup toi bai toan nay (15x^3+x^2-...+...):(3x^2+2x-10) dien tu thich hop thanh phep chia het
Tim x biet: 720:(x + 3 + x x 5) =6 giup toi giai bai toan nay voi
a 9,15 x X + 2,85 = 47,685
giup toi giai bai toan tim X tren nhe
9 , 15 x X + 2 , 85 = 47 , 685
9 , 15 x X = 47 , 685 - 2 , 85
9 , 15 x X = 44 , 835
X = 44 , 835 : 9 , 15
X = 4 , 9
Vậy X = 4 , 9
Chúc bạn học tốt nha !!!
giup toi giai bai toan nay:
cho a:b=9:4 va b:c=5:3 hay tim ti so (a-b):(b-c)

Giup toi giai bai toan:
1+2/6+2/12+.....+2/x(x+1)=3980/1991
Cac ban giup toi co loi giai doi voi bai toan nay nhE
(x-3)2=25
\(\left(x-3\right)^2=25\)
\(\Rightarrow\left(x-3\right)^2=5^2\)
\(\Rightarrow x-3=5\)
\(\Rightarrow x=8\)
(x - 3)2 = 25
(x - 3)2 = 52 = (-5)2
=> x - 3 thuộc {5 ; -5}
=> x thuộc {8 ; -2}
Vậy x thuộc {8 ; -2}
(x-3)2=25
x-3=5 (vì 25=52) hoặc x-3=-5 (vì 25=(-5)2
x=8 hoặc x=-2
