\left(-y^{-4}\right)^{-2}\left(t^{3}\right)^{-2}
Expand \left(\left(-y^{-4}\right)t^{3}\right)^{-2}.
\left(-y^{-4}\right)^{-2}t^{-6}
To raise a power to another power, multiply the exponents. Multiply 3 and -2 to get -6.
\left(-1\right)^{-2}\left(y^{-4}\right)^{-2}t^{-6}
Expand \left(-y^{-4}\right)^{-2}.
\left(-1\right)^{-2}y^{8}t^{-6}
To raise a power to another power, multiply the exponents. Multiply -4 and -2 to get 8.
1y^{8}t^{-6}
Calculate -1 to the power of -2 and get 1.
y^{8}t^{-6}
For any term t, t\times 1=t and 1t=t.
