15 7/4
1
15^3

Answer 1

15³

Explanation:

`\sf \frac{ {15}^(7) }{ {15}^(4) }`

`= \sf (15 * 15 * 15 * 15 * 15 * 15 * 15)/(15 * 15 * 15 * 15)`

`= \sf \frac{ \sout{15} * \sout {15} * \sout{15} * \sout{15} * 15 * 15 * 15}{ \sout{15} * \sout {15} * \sout{15} * \sout{15 } }`

`= \sf \: 15 * 15 * 15`

`\sf \: = {15}^(3)`
