Giup minh voi. Ai lam xong nhanh va chinh xac nhat minh se tick. THANK YOU
giup mk nhanh voi minh can gap lam:tim x thuocZ biet:
10-x-|x+5|=0 va |x-7|+|x+3|=8
X-2=-7-13
moi nguoi giup minh nhe va ket ban voi minh luon ai ma tra loi nhanh nhat minh se bam tick
tim gia tri nho nhat cua:
F = |x| + |x + 2|
cac ban giup minh voi nhe minh dang can gap lam
Các bn giup mk vs. Mk dag can gap
Tim x€Z biết:
-12.(x-5)+7.(3-x)=5
Ai nhanh,đung minh tick cho
tim x
a) 3^x -4 =5^7 : 5^6
b ) 3^x-1 =27
c) (x-1) ^3 = 4(x-1)
d) 5^x 5^x-2= 130
ai giup mk nhanh nhat mk se tick cho 4 lan luon
1, tim x
5+x-3=5-(x+4)
x-(5|-7|+3)=|-8|+6-2
|x-3|+7
12-3|x-1|=6
cac ban giup minh nhe nho cac buoc tinh ro rang nha minh se like cho
TIM X
a) 5x = 6x
b) x3 = x6
LAM ON GIUP MINH VOI!
bai 1, tim x, biet
a, (-x+31)-39=-69 b, -120-(-30-x)=-50 c, /x/ -5=-1 d, /x+2/-12=-1
e, \(\left(3x-2^4\right).7^3=2.7^5\)
