5³ + 5³ + 5³ + 5³ + 5³ = 5ⁿ

taking 5³ as common,

5³(1+1+1+1+1) = 5ⁿ

5³(5) = 5ⁿ

5 =  \frac{ {5}^{n} }{ {5}^{3} }

we \: know \: that \:  \frac{ {a}^{m} }{ {a}^{n} }  =  {a}^{m - n}

5 =  {5}^{n - 3}

5 can be written as 5¹

 {5}^{1}  =  {5}^{n - 3}

taking the powers alone,

1 = n - 3

1 + 3 = n

4 = n

Hope it helps!!

have a great day!!
