Tìm x biết : x-2/327 + x-3/326 + x-4/325 + x-5/324 + x-344/5 =1
Tìm x biết a) x+2/327 + x+3/326 + x+4/325 + x+5/324 + x+349/5 = 0
28) (x+1/5)2 + 17/25=26/25
35) x+2/ 327+ x+3/326+x+4/325+x+5/324+x+349/5=0
1. tìm x biết x+2/327 + x+3/326 + x+4/325 + x+5/324 + x+349/5 = 0
2.CMR:n thuộc N* thì 3^n+2 - 2^n+2 + 3^n - 2^n chia hết cho 10
tìm x e Q
a) \(\dfrac{x+1}{3}+\dfrac{x+1}{4}+\dfrac{x+1}{5}=\dfrac{x+1}{6}\)
b) \(\dfrac{x+1}{2020}+\dfrac{x+2}{2019}=\dfrac{x+3}{2018}+\dfrac{x+4}{2017}\)
c) \(\dfrac{x+2}{327}+\dfrac{x+3}{326}+\dfrac{x+4}{325}+\dfrac{x+5}{324}+\dfrac{x+349}{5}=0\)
Tính nhanh -326 -(115 -326)
Thực hiện phép tính:
328+ [54 +(-328)+[-44 ]
Tìm x:
a) \(\frac{x+2}{327}+\frac{x+3}{326}+\frac{x+4}{325}+\frac{x+5}{324}=4\)
b) \(\left|x^2-5x\right|+\left|\left(x-2\right)\left(x-5\right)\right|=0\)
B1. Tìm x,biết :
a, \(\frac{x+2}{327}+\frac{x+3}{326}+\frac{x+4}{325}+\frac{x+5}{324}+\frac{x+349}{5}=0\)
b, \(|5x-3|\ge7\)
giúp mình giải chi tiết nha mai phải nộp rồi
128+(-328)+72+/-328/+(-148)=
