Penjelasan dengan langkah-langkah:

Nomor 1

${5}^{3} + {5}^{3} + {5}^{3} + {5}^{3} + {5}^{3} = {5}^{n}$

$5. {5}^{3} = {5}^{n}$

${5}^{1 +3 } = {5}^{n}$

${5}^{4} = {5}^{n}$

$n = 4$

$:$

Nomor 2

${5}^{4} + {5}^{4} + {5}^{4} + {5}^{4} + {5}^{4} = {5}^{n}$

$5. {5}^{4} = {5}^{n}$

${5}^{1 + 4} = {5}^{n}$

${5}^{5} = {5}^{n}$

$n = 5$
