\(\left(x+4\right):x\)
\(=x:x+4:x\)
\(=1+4:x\)
\(\left(x+4\right):x\)
\(=x:x+4:x\)
\(=1+4:x\)
2 phần ( x + 2 ). ( x + 4 ) + 4 phần ( x + 4 ) .( x + 8 ) + 6 phần( x + 8 ) .( x + 14 ) = x phần( x + 2 ) ( x + 14 ) với ( x ∉ { − 2 , − 4 , − 8 , − 14 } ) .
Tìm x, biết
x/4 = 9/4
a. x=6
b. x=3; x=-7
c. x=6; x=-6
d. x=5;x=-7
e. x=4; x=-4
Tinh gia tri cua phan so: A= 2 x 3 + 2 x 4 x 8 + 4 x 8 x 16 + 8 x 16 x 32/ 3x 4 + 2 x 6 x 8 + 4 x 12 x 16 + 8 x 24 x 32
tim x biet 2/(x+2)+(x+4)+4/(x+4)+(x+6)+6/(x+6)+(x+14)=x/(x+2)+(x+14)
A = 4 x 4 x ... x 4 (2023 chữ số 4)
B= 3 x 15 x 23 x ... x 2023
Em xin cách giải ạ
X=5
X-4+X-4=...×(X-4)=...(-5-4)=...
x=5
x-4+x-4=...×(x-4)=...×(-5-4)=...
a,1/3 .(x-2/5)=3/4 b, 7/3:(x-2/3)=4/5 c,1/3.(x-2/5)=4/5 d, 2/3.(x-1/2)-1/4.(x-2/5)=7/3 e,3/7 .(x-2/3)+1/2=5/4.(x-2) f,1/2.(x-3)+1/3.(x-4)+1/4.(x-5)=1/5 g,[2/3.(x-1/2)-4/5]:(x-1/3)=21/5 h, {x-[1/2.(x-3)+11/5]}:(x-1/2)=3/5 i,x.(x-2/5)-(x+2).x+11/4=4/3
tìm x để:
(x+3).(4-x)=(1-x).(x-7)
(2x-1).(x-1)=(x+2).(2x+3)
(4-x).(3-x)=(1-x).(10-x)
(x+1).(x+4)=(x+2).(x+3)
(1-3x).(x+4)=(x+2).(-3x+2)
Mọi người giúp mik bài nài nhé !
3 x 25 x 8 + 6 x 4 x 37 + 2 x 38 x 12.A = 1 x 2 + 2 x 3 + 3 x 4 + 4 x 5 + 5 x 6 +...+ 99 x 100B = 1 x 3 + 2 x 4 + 3 x 6 + 4 x8...+ 99 x 101 C = 4 + 12 + 24 + 40 + ... + 19404 + 19800
