Tìm x:
a) ( 3x - 1 )^3 = 27
b) 3 ^2x - 1 = 27
c) 6 ^8 - 2x = 36
d) ( 3x - 2 )^10 = ( 3x - 2 )^7
*Đằng sau dấu "^" ý chỉ là những số mũ nhé!!!
7-(2x-1/3)^2=3
(2x+1/3)^2-3/8=1/8
12:[29-(x-2/3)^2]=3
(3x-1/2)^3+8/3=29/9-14/27
2(2x-1/3)^2+4/3=5/6+13/18
Tìm X
(3x-10)3 = \(\dfrac{-8}{27}\)
tim x :
( 2x+3)2=9/121
( 3x-1)3=-8/27
1. 3x-9=(-1)-x
2. 2x-23= 17-3x
3. | x-3 | + 8 = 12
4. 12-2 | x | = | -2012 |
5. 19- (14+19)=x-(27-9)
6.15-|x-3|=2
7. | x-5 | - 27 = (-6)
8. 3. | x - 2 | = | -15 |
9. 11 - 2 | x | = (-3)
10. | x - 2 | = 1
Ai giải có lời giải nha chư không phải kết quả không thôi, giải hết mình tick
Bài 8. Tìm số nguyên x
1) x – 12 = (-8) + (-17) 2) (7 – x) – 5 = - 13 3) 7 – 3x = 28 4) 2(x + 1) + 18 = - 4 | 5) 37 – x = 12 6) x + 5 = -18 7) 27 – (x + 1) = 2. (52 – 24) 8) (x – 3)(x + 3) = 0
|
a) x3=27, b) (2x-1)3=8,c)(x-2)2=16,d) (2x-3)2=9,e)2x+5=34:32,f)(3x-24.73=2.74
tìm x
a) 5/8 - x = 2 1/6
b) 4/9 : x = -1/3+1 1/6
c) (3x-2)^3 = -1 / 27
d)/3x-4/ = 16 1/9 + 18/19
e) /2x + 1/=x+2
\(8^{2x+1}=2^{27}:4^6\)
\(x^{10}=x\)
\(\left(3x-1\right)^3=25\left(3x-1\right)\)
