Answer 1

Answer:

$\large\boxed{10t}$

Step-by-step explanation:

$Use:\\\\(a^n)^m=a^{nm}\\\\(ab)^n=a^nb^n$

$\Bigg[\bigg(1\underbrace{00,000,000}_{8}t^8\bigg)^{-\frac{1}{2}}\Bigg]^{-\frac{1}{4}}=\bigg(10^8t^8\bigg)^{\left(-\frac{1}{2}\right)\left(-\frac{1}{4}\right)}=\bigg(10t\bigg)^{8\left(\frac{1}{8}\right)}=\bigg(10t\bigg)^1$
