Answer: [tex]4x^2y^4[/tex]
Step-by-step explanation:
Given
The area of the square is [tex]A=16x^4y^8[/tex]
Suppose a is the side length of the square
The area of the square is given by
[tex]\Rightarrow A=(\text{side length})^2[/tex]
So, we can write
[tex]\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4[/tex]
length of each side is [tex]4x^2y^4[/tex]
