Tìm x, biết
1/(2.4) + 1/(4.6) + … + 1/[(2x – 2).2x] = 1/8 (x ∈ N, x ≥ 2)
ai giúp mik vs.....
Tìm x, biết
1/(2.4) + 1/(4.6) + … + 1/[(2x – 2).2x] = 1/8 (x ∈ N, x ≥ 2)
tìm x
1/2.4+1/4.6+.......+1/(2x-2).2x =1/8(x thuộc N ,x> bằng 2)
Tìm x
\(\dfrac{1}{2.4}\) + \(\dfrac{1}{4.6}\) +...+ \(\dfrac{1}{\left(2x-2\right).2x}\) = \(\dfrac{1}{8}\) ( x ∈ N , x ≥ 2 )
có lời giải chi tiết
Tìm x, biết:
\(\dfrac{1}{2.4}+\dfrac{1}{4.6}+...+\dfrac{1}{\left(2x-2\right).2x}=\dfrac{11}{48}\) (x ϵ N , x ≥ 2)
1/(2.4) + 1/(4.6) + … + 1/[(2x – 2).2x] = 1/8 (x ∈ n, x ≥ 2)
1/(2.4) + 1/(4.6) + … + 1/[(2x – 2).2x] = 1/8 (x ∈ N, x ≥ 2)
Tìm x biết:
\(\frac{1}{2.4}+\frac{1}{4.6}+...+\frac{1}{\left(2x-2\right).2x}=\frac{1}{8}\left(x\in N,x\ge2\right)\)
Tìm x, biết:
1/2.4+1/4.6+...+1/(2x-2).2.x Giúp mk nha
1/(2.4) 1/(4.6) … 1/[(2x – 2).2x] = 1/8 (x ∈ N, x ≥ 2)
