a) (7/2+2x)x8/3=16/3
b) [2x+3]=5
c) x-2/4=5+x/3
a. x \(\div\)( 1/1*3 + 1/3*5 + ...... + 1/101*103 ) =1 .
b.( 1/1*2 + 1/2*3 + 1/3*4 + ........ + 1/11*12) * x =2
c. x : 3/4 = 2x * 7/3 +5
Cac ban giai theo dang tim x nha . Cam on nhieu. Nhanh nhe vi minh can gap
Tim x
A, 6 x + x = 5^11 : 5^9 +3^1
B, 7 x - x = 5^21 : 5^19 + 3 . 2^2 -7^0
C, 7 x - 2x = 6^17 : 6^15 + 44 : 11
giup minh nhe . Thank you
tim x biet
a)20÷(2x-3)=4
b)2017-69×(11-x)=27÷23
Giai nhanh giup minh nhe!
{x^2 -[ 6^2-(8^2-9*7)^3-7*5 ]^3-5*3 }^3=1
giup toi nhe
cac ban giu toi giai bai tap nay nhe.
tim x thuoc z
A) |2x-5|=13
(x-1)*(x ^2+1)=0
Giup minh voi toi nay minh rat can, dung thi minh tich cho, ca cach lam nua nhe.
Tim x,y
a, 2x.y+xy=7
b, xy + 2x - 7y = 14
c, x^3 - 64x = 0
Tìm x là stn
6x : 33 :4 = 2

7x - 2x=617: 615+ 38 : 26
Giup minh vơi a , co cach lam nhe a
