Đẹp Trai Vô Đối nói dối như điên à

\(\left(8x-1\right)^{2n+1}=5^{2n+1}\)

\(\Rightarrow8x-1=5\Rightarrow8x=6\Rightarrow x=\frac{3}{4}\)

 Vậy x = 3/4

\(\left(8x-1\right)^{2n+1}=5^{2n+1}\)

\(=>8x-1=5\)

\(=>8x=6\)

\(=>x=\frac{3}{4}\)

Bài này dễ mà

<=> 8x-1 = 5 <=> 8x = 6 <=> x= 3/4

vì 2n+1 lẻ nên 8x-1=15\(\Rightarrow\)x=2

(8x-1)²ⁿ⁺¹ = 15²ⁿ⁺¹ 

=> 8x - 1 = 15

8x = 16

x= 2 

\(\left(8x-1\right)^{2n+1}=5^{2n+1}\)

\(\Leftrightarrow8x-1=5\)

\(\Leftrightarrow x=\frac{3}{4}\)

\(\left(8x-1\right)^{2n+1}=5^{2n+1}\)

\(\Rightarrow8x-1=5\)

\(\Rightarrow8x=6\)

\(\Rightarrow x=\frac{3}{4}\)

Vậy \(x=\frac{3}{4}\)

(8x - 1)²ⁿ⁺¹ = 5²ⁿ⁺¹ ( lũy thừa bậc lẻ )

8x - 1 = 5

8x = 6

x = 3/4

\(\left(8x-1\right)^{2n+1}=5^{2n+1}\Rightarrow8x-1=5\Rightarrow8x=6\Rightarrow x=\frac{6}{8}\)

healp 

(8x - 1)²ⁿ⁺¹ = 5²ⁿ⁺¹

8x - 1 = 5

8x - 1 = 5

8x = 6

x = \(\frac{3}{4}\)

n là số tự nhiên số mũ 2n + 1 > 0 

=> (8x-1)²ⁿ⁺¹=5²ⁿ⁺¹ => 8x - 1 = 5 => 8x = 6 => x = 6/8 = 3/4

Vậy x = 3/4

(8x-1)²ⁿ⁺¹=5²ⁿ⁺¹(n\(\varepsilon\)N)

=>(8x-1)=5

     8x=6

    Vậy x=\(\frac{3}{4}\)

\(\left(8x-1\right)^{2n+1}=5^{2n+1}\)

\(8x-1=5\)

\(8x=6\)

\(x=\dfrac{3}{4}\)

=.= hok tốt!!
