Answer 1

25=$5^{2}$
$81=3 ^{4}$
$16= 2^{4}$
$4= 2^{2}$
$7= 7^{1}$
$1=1^{1}$
$0.25=0.5^{2}$
$1.44= 1.2^{2}$
$2.25= 1.5^{2}$
$\frac{1}{9} = \frac{1}{3 ^{2} }$
$\frac{1}{121}=( \frac{1}{11} )^{2}$
$\frac{1}{4} = (\frac{1}{2}) ^{2}$
$\frac{1}{8} = ( \frac{1}{2}) ^{3}$
$\frac{1}{49} = (\frac{1}{7}) ^{2}$
$\frac{1}{36} = (\frac{1}{6}) ^{2}$
$\frac{1}{100} =( \frac{1}{10}) ^{2}$
$0.01=0.1 ^{2}$
$0.1= 0.1^{1}$
$0.001= 0.1^{3}$
$0.0001=0.1 ^{4}$
