Question

Don't know, could someone help me!!

Answer 1

`\boxed{A=1~~\land~~B=-4}`

Explanation:

I use formulas:

`\boxed{(x^(n) )/(x^(m) ) =x^(n) / x^(m) =x^(n-m) }`

`(t^(2) )/(t^(6) ) =t^(2)/ t^(6)=t^(2-6)=\boxed{t^(-4)}\\\\t^(-4) =1\cdot t^(-4) ~~\land~~At^(B) ~~\Rightarrow ~~A=1~~\land~~B=-4`
