please answer this question fast please please please please​

Answer 1

Step-by-step explanation:

⇒ $7^{2n+1}$ ÷ 49 = $7^{3}$

⇒  $7^{2n+1}$ × $\frac{1}{7^{2} }$ = $7^{3}$

⇒ $7^{2n+1}$ × $7^{-2}$ = $7^{3}$

Therefore,

2n+1 + (-2) = 3

2n+1 -2 = 3

2n - 1 = 3

2n = 4

n = 4/2

n = 2

Hope it helps :)

Have a good day.
