Answer:
A. [tex]\frac{x^{2n+10}}{y^2}}[/tex]
Step-by-step explanation:
We have been given an expression [tex](\frac{x^{n+5}}{y}})^2[/tex].
Using exponent property [tex](a^b)^c=a^{b*c}[/tex], we will get:
[tex]\frac{x^{2\cdot n+5\cdot 2}}{y^2}}[/tex]
[tex]\frac{x^{2n+10}}{y^2}}[/tex]
Therefore, simplified form of our given expression would be [tex]\frac{x^{2n+10}}{y^2}}[/tex].
