Question

Evalue each expression for the given value(s) of the variable(s)exponents

Answer 1

Any number raised to the power of zero equals 1, then

`r^0s^(-2)=1\cdot s^(-2)=s^(-2)`

then, we need to substitute the value 10 in the variable s. It yields,

`s^(-2)=(1)/(s^2)\Rightarrow(1)/(10^2)=(1)/(100)`

Then, the answer is

`r^0s^(-2)=(1)/(s^2)\Rightarrow(1)/(100)`

that is, 1 / 100.
