\(\frac{1440}{41-\left(x-5\right)}=2^4.3\)
\(\Rightarrow\left[41-\left(x-5\right)\right]2^4.3=1440\)
\(\Rightarrow\left[41-\left(x-5\right)\right].48=1440\)
\(\Rightarrow41-\left(x-5\right)=30\)
\(\Rightarrow x-5=11\)
\(\Rightarrow x=16\)
Vậy \(x=16\)
ai giúp mình bài này với
t) 1440:[ 41 - ( 2x -5)] = 2^4 .3
tim x
a, ( 2x - 4 ) ^ 3 = 8
b, 720 / [ 41 - ( 2x - 5 ) ] = 2^3 * 5
b) 1500.(x – 7) = 0
c) (2.x – 4).(48 – 12.x) = 0
d) (x + 12).(x – 1) =0
Bài 2: Tìm x biết:
a) 128- 3(x+ 4) = 23
b) [(14x+ 26). 3+ 55]: 5= 35
d) 720: [41- (2x- 5)]= 23. 5
tìm x biết 2016x +(7/12+4/21+2/24+11/30+3/41+15/56)-(2/3+2/4+2/5)=0
nhanh nha!!!!
1, Tìm x
a, (2x+1)3=243
b, 2x+2 - 2x = 96
c, 720 : [41- (2x-5)] = 23. 5
thanks
3 tick
Tìm x biết
A, x/4 - 3/7 + 2/5 = 31/140
B, 5/12 + 5/x - 1/8 = 1/2
C, x + 4/5×9 + 4/9×13 + 4/13×17 +.....+ 4/41×45 = -37/45
\(Tính: B = \dfrac{2 - \dfrac{2}{19} + \dfrac{2}{43} - \dfrac{2}{2017}}{3 - \dfrac{3}{19} + \dfrac{3}{43} - \dfrac{3}{2017}} :\dfrac{4 - \dfrac{4}{29} + \dfrac{4}{41} - \dfrac{4}{2018}}{5 - \dfrac{5}{29} + \dfrac{5}{41} - \dfrac{5}{2018}} \)
Tìm số nguyên x , biết:
13) 720 : [ 41 - ( 2x - 5) = 2\(^3\) . 5
14) { [ 2x + 14) : 2\(^2\) - 3] : 2} - 1 = 0
Tìm các số nguyên x, biết:
a, -2.(x + 6) +6.(x-10) = 8
b, -3x +5 = 41
c, |2x - 5| = 13
d, |7x + 3| = 66
e, |7x + 1| = 20
