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