Answer:

10¹²  

Step-by-step explanation:

[tex]f(t) = \left [t(t^{2})\right ]^{-2}\\[/tex]

Start with the inner parentheses and work out.

1. Apply the product rule.

[tex]\left [t(t^{2})\right ]^{-2} = \left [t^{3}\right ]^{-2}[/tex]

2 . Apply the power rule

[tex]f(t) = \left [t^{3}\right ]^{-2} = t^{-6}[/tex]

3. Substitute the value of t

[tex]f(10^{-2}) = (10^{-2})^{-6}[/tex]

4. Apply the power rule.

[tex]10^{-2 \times (-6)} = \mathbf{10^{12}}[/tex]
