What is 3(-6)2 at the top ?

[tex]\huge\boxed{108}[/tex]
The [tex]^{-2}[/tex] only affects the [tex](-6)[/tex]. Let's solve that exponent first.
[tex]3(-6)^{-2}[/tex]
[tex]3(-6*-6)[/tex]
Multiply.
[tex]3*36[/tex]
Multiply one last time.
[tex]\boxed{108}[/tex]
Answer:
108
Step-by-step explanation:
Do the parentheses first with the exponent of 2 on the outside.
Multiply -6 times -6, which gets you 36.
After, multiply 36 by 3. Which gets you 108!
Final: 108
