Question

Which expression equivalent to 9x^5 y^16 over 45x^5 y^4

Answer 1

`\large\boxed{(1)/(5)y^(12)}`

Explanation:

`\text{Use}\ (a^n)/(a^m)=a^(n-m)\\\\(9x^5y^(16))/(45x^5y^4)=(9\!\!\!\!\diagup^1)/(45\!\!\!\!\!\diagup_5)x^(5-5)y^(16-4)=(1)/(5)y^(12)`

Answer 2

the answer after simplify is:

`\frac{ 9{x}^(5) {y}^(16) }{45 {x}^(5) {y}^(4) } = \frac{ {y}^(12) }{5}`
