Question

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

Answer 1

the answer after simplify is:

$\frac{ 9{x}^{5} {y}^{16} }{45 {x}^{5} {y}^{4} } = \frac{ {y}^{12} }{5}$

Answer 2

Answer:

$\large\boxed{\dfrac{1}{5}y^{12}}$

Step-by-step explanation:

$\text{Use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\\dfrac{9x^5y^{16}}{45x^5y^4}=\dfrac{9\!\!\!\!\diagup^1}{45\!\!\!\!\!\diagup_5}x^{5-5}y^{16-4}=\dfrac{1}{5}y^{12}$
