tim so tu nhien x thoa man 3^x+4^x=5^x
tim x thoa man dang thuc |x+1|+|2x+3|+|3x+5|=16x-1
Giúp mk vs nhé!!!
a) tim gia tri nho nhat cua bieu thuc
A= | 2x-2 | + | 2x-2019 |
b) tim x lon nhat thoa man
| 2x-4 | - | 6-3x | = -1
tim x,y thoa man:/x-1/+/x-2/+/y-3/+/x-4/=3
Tim gia tri x duong thoa man?
|x-9|+(-|2x|)=0
tim x thoa man: 2*Ix-1I - I 2x - 5I = 3
tim cap so nguyen x,y thoa man: |x+4|+|y-2|=3
tim x thoa man : -x-3/4=-8/11. khi do 11.x=
tim x biet:
a) (4x-3)^4=(4x-3)^2
b) co hay khong so huu ti thoa man?
(2x+3)^2+(3x-2)^4=0
YOU DO FAST. THANKS
