If $n$is an integer and $a≠0$, then

$a^{-n}=\frac{1}{a^n}or\frac{1}{a^{-n}}=a^n$

The given expression is $s^{-8}$.

We have to simplify the given expression using negative exponents

Using Property for negative exponents,

$s^{−8}=\frac{1}{s^8}$

So, the simplified expression is$s^{−8}=\frac{1}{s^8}$

The given expression is${10}^{-2}$ .

We have to simplify the given expression using negative exponents

Using Property for negative exponents,

${10}^{−2}=\frac{1}{{10}^2}$

So, the simplified expression is${10}^{−2}=\frac{1}{{10}^2}$

The given expression is$\frac{1}{t^{-9}}$ .

We have to simplify the given expression using negative exponents

Using Property for negative exponents,

$\frac{1}{t^{−9}}=t^9$

So, the simplified expression is$\frac{1}{t^{−9}}=t^9$

The given expression is $\frac{1}{{10}^{-4}}$ .

We have to simplify the given expression using negative exponents

Using Property for negative exponents,

$\frac{1}{{10}^{−4}}={10}^4$

So, the simplified expression is$\frac{1}{{10}^{−4}}={10}^4$
