Answer:
[tex]\boxed{A=1~~\land~~B=-4}[/tex]
Step-by-step explanation:
I use formulas:
[tex]\boxed{\dfrac{x^{n} }{x^{m} } =x^{n} \div x^{m} =x^{n-m} }[/tex]
[tex]\dfrac{t^{2} }{t^{6} } =t^{2}\div t^{6}=t^{2-6}=\boxed{t^{-4}}\\\\t^{-4} =1\cdot t^{-4} ~~\land~~At^{B} ~~\Rightarrow ~~A=1~~\land~~B=-4[/tex]
