9x^8 = (3x^4)^2
25x^12 = (5x^6)^2
36x^16 = (6x^8)^2

answer
9x^8
25x^12
36x^16 

Answer: Options Third, Second , Fourth are correct.

Step-by-step explanation:

Since we have given that

[tex]6x^2\\\\9x^8\\\\16x^9\\\\25x^{12}\\\\36x^{16}[/tex]

Since we know that

9, 16, 25, 36 are perfect squares.

So, we get that

[tex]9x^8=(3x^4)^2\\\\25x^{12}=(5x^6)^2\\\\36x^{16}=(6x^8)^2[/tex]

Hence, Options Third, Second , Fourth are correct.
