\(y=\frac{1}{x^2+\sqrt{x}}\frac{\sqrt[]{}\int^{ }_{ }}{ }\)\(y=\frac{1}{x^2+\sqrt{x}}^2_{ }\theta\sqrt{\frac{ }{ }}\)
tính nhanh : 88986 x 2003 - 678\(y=\frac{1}{x^2+\sqrt{x}}\frac{iu}{uk}\)
Tìm Y: \(Y x \frac{2}{5} - Y x \frac{4}{15} = \frac{3}{2}\)
\(\frac{2}{3} : Y + \frac{7}{8} : Y = \frac{1}{2}\)
Giúp nhanhh xD
\(y=\frac{1}{x^2+\sqrt{x}}\)
Tìm y:
y X\(\frac{52}{26}=\frac{17}{13}\)
\(4\frac{1}{2}:y=\frac{2}{7}\)
bài 1 tìm x,y,z biết
a, 3x=4y=6zvaf 2x - 5z = -36
b, \(\frac{x+y+4}{z}=\frac{y+z-5}{x}=\frac{z+x+1}{y}=\frac{6}{x+y+z}\)
bài 2cho \(\frac{a}{b+c}=\frac{b}{c+a}=\frac{c}{a+b} \)
tính M=\(\left(1+\frac{a}{b}\right)\left(1+\frac{b}{c}\right)\left(1+\frac{c}{a}\right)\)
Tìm y là số tự nhiên :
\(\frac{1}{2}x\frac{1}{3}< y< \frac{1}{4}:\frac{1}{8}\)
Tìm y :
a, \(\frac{3}{5}\) x y + \(\frac{1}{2}\): \(\frac{5}{3}\)- \(\frac{5}{4}\) = \(\frac{1}{2}\)x \(\frac{1}{3}\)
b , \(\frac{4}{5}\): y + \(\frac{1}{4}\)x \(\frac{1}{6}\)- \(\frac{1}{2}\)= \(\frac{1}{3}\)x \(\frac{5}{2}\)
c. \(\frac{3}{5}\)x y - \(\frac{4}{5}\): 3 + \(\frac{1}{12}\)= \(\frac{3}{2}\)+ \(\frac{1}{5}\)
* Ai giải đúng nhất mk k !
1. Tìm số tự nhiên n, thỏa mãn : \(\frac{95}{13}\times\frac{105}{31}>n>\frac{100}{31}:\frac{50}{217}.\)
2. Tìm y:
\(y+y:\frac{2}{7}+y\times\frac{3}{5}=102\)
