Step-by-step explanation:
A.
[tex](6^2)^x=1\\\\36^x=1\\\\36^x=36^0\Rightarrow x=0[/tex]
Every number to the power of 0 gives us 1
[tex]a^0=1\ \text{for}\ a\in\mathbb{R}[/tex]
B.
[tex](6^0)^x=1\\\\1^x=1\\\\x\in\mathbb{R}[/tex]
1 to the any power gives us 1.
[tex]1^n=1\ \text{for}\ n\in\mathbb{R}[/tex]
