Answer:
8
Explanation:
We observe that the logarithm bases are ...
5√5 = √125 . . . . . 125 is the 2nd power of this
2√2 = √8 . . . . . . . 8 is the 2nd power of this; 64 is the 4th power of √8
If we define ...
![p=√(125)\\q=√(8)](https://img.qammunity.org/2020/formulas/mathematics/high-school/6obz062p4egnw2zuj39wegc5hcpg584lw6.png)
Then our logarithms are ...
![log_p(p^2)=x=2\\\\log_q(q^4)=y=4\\\\xy=2\cdot 4=8](https://img.qammunity.org/2020/formulas/mathematics/high-school/m04g5jk7tor7dqiso3hj3mx1odku78va6h.png)
The product of x and y is 8.
