(x-1)x+2=(x-1)x+4
1/ 4 . 2/6 . 3/8 . 4/10 . 5/15 .... 30/62 . 31/64= 2x
Tìm x biết
a) \(\frac{x+1}{2x+1}=\frac{\frac{1}{2}x+2}{x+3}\)
b) \(x^2+5x=0\)
c) \(\frac{1}{4}.\frac{2}{6}.\frac{3}{8}.\frac{4}{10}.\frac{5}{12}...\frac{30}{62}.\frac{31}{64}=2^x\)
tìm x
a, x2 + x = 0
b, (x-1)x+2 = (x-1)x+4
c, 1/4. 2/6. 3/8. 4/10. 5/12..... 30/62. 31/64=2x
d, x-1/ x+5= 6/7
e, x2/ 6= 24/25
g, x-2/ x-1= x+4/ x+7
Tìm x biết rằng
a)\(\frac{1}{4}.\frac{2}{6}.\frac{3}{8}.\frac{4}{10}.\frac{5}{12}...\frac{30}{62}.\frac{31}{64}=2x\)
b)\(\left(x-1\right)^{x+2}=\left(x-1\right)^{x+4}\)
Ta có: (1/4)*(2/6)*(3/8)*(4/10)*(5/12)*...*(30/62)*(31/64)=2^x. Tìm x
Tìm x:
\(a,\left|x-3\right|-2x=\left|x-4\right|\)
\(b,\frac{1}{4}\times\frac{2}{6}\times\frac{3}{8}\times\frac{4}{10}\times...\times\frac{30}{62}\times\frac{31}{64}=2^x\)
Tìm x:
1/4 . 2/6 . 3/8 . ... . 30/62 . 31/64 = 4x
tìm x biết :
(1/4).(2/6).(3/8).(4/10).(5/12)....(30/62).(31/64) = 2^x
