I think you mean $\frac{5^{-1}}{5^0}$

ok, know some stuff
x^0=1

for all real values of x
$x^{-m}=\frac{1}{x^m}$

so

$\frac{5^{-1}}{5^0}=$
$\frac{\frac{1}{5^1}}{5^0}=$
$\frac{\frac{1}{5}}{5^0}=$
$\frac{\frac{1}{5}}{1}=$
$\frac{1}{5}$

it results in 1/5

or, we could have done
$\frac{x^m}{x^n}=x^{m-n}$ and
$x^{-m}=\frac{1}{x^m}$
so
$\frac{5^{-1}}{5^0}=5^{-1-0}=5^{-1}=\frac{1}{5^1}=\frac{1}{5}$

the result is $\frac{1}{5}$

(X+2)/3x+6=(x+2)/3(x+2)
=1/3
We have x+2 in both numerator and denominator so we cancel them out and are left with 1/3

2.) (x-1)/2x-2
=(x-1)/2(x-1)
=1/2
Same as in first question
