(3/5-2/3.x)3=-64/125
(3/5-2/3.x)3=(-4/5)3
3/5-2/3.x=-4/5
2/3.x=3/5-(-4/5)
2/3.x=7/5
x=7/5:2/3
x=21/10
\(\left(\frac{3}{5}-\frac{2}{3}x\right)^3=-\frac{64}{125}\)
(x + 5)3 = \(\dfrac{-64}{125}\)
(5^4-5^3)^3/125^4-64/125
Chứng minh : \(\frac{\left(5^4-5^3\right)}{125^4}=\frac{64}{125}\)
Tìm x
a)\(^{3^x}+^{3^{x+2}}=810\)
b)\(\left(x+\frac{2017}{2018}\right)^6=0\)
(5^4-5^3/125^4)=64/125
(54-53)3/1254 - 64/125
1/3 .2x+5/3.2x+2=1/2 . 26 + 2 . 613
(1/3 - 1/6 ) . 2x + 2x+1=212+210
5/3 .8x+2-3/5 . 8x = 5/3 . 811 -3/5.83
Chứng minh
Chứng minh ( 245x5424x210) chia hết 7263
Chứng minh (54-53)3/125 = 64/125
Vì sao : (5^4×5^3)^3/125^4=64/125
Mong các bạn giúp mình ạ :<
(3/5 - 2/3x)^3 = -64/125
giúp mk với ai nhanh mk tk cho
