4 x-(2 x+1)= 3 -\(\frac{1}{3}\)+ x
Giai bai nay giup mik nha mai mik kiem tra toan 2 tiet roi
Ai giai giup minh bai nay voi
A=1+1/2(1+2)+1/3(1+2+3)+......+1/2011(1+2+3+.....+2011)
giup to bai nay nha :
20 - |y-2| = 4.(x-1)4
a ) ( -3/4 ) 3x-1 = 256/81
b) 2 .22.23......2x=1024
bai nay tim x nha :
giup minh voi
bai 1: Tim x
a) (x-1)^3 =27
b ( 2x +1)^2=25
c) (x-1)^x+2=(x-1)x+4
d) ( 2x-1)^3 =-8
e) 2^2x-2x=96
GIUP MK VOI NHA MK DANG CAN GAP LAM
Cho:
A=1/2+1/3+1/4+...+1/200
B = 1/199+2/198+3/197+...+ 197/3+198/2+199/1
Tinh A/B
Bai nay kho nen cac ban giai giup minh nha minh tich dung cho
\(\left(x-2011\right)^{x+1}-\left(x-2011\right)^{x+2011}=0\)
Lam bai co loi giai giup minh nha
3/7:4/49
1/2-(1/3)<x<1/48-(1/16)
giup mik nhe , ai giup mik tik cho!!!!!!!!!!!!
Giúp Mik nha mn
Câu 1:
a, 2x-1=16
b,(x-1)2=25
c,(x-1/2)3=1/27
d,(x-1)x+2=(x-1)x+6 ;
đ,(x+1/2)2=4/25
