Answer
$a.\,\,4\\
b.\,\,10\\
c.\,\,-3\\
d.\,\,0\\
e.\,\,-1\\
f.\,\,1\\
g.\,\,k\\$
Work Step by Step
$a-\log_{3}81=4\\
because\,\,3^4=81\\
b-\log_{2}1024=10\\
because\,\,2^{10}=1024\\
c-\log_{3}\frac{1}{27}=-3\\
because\,\,3^{-3}=\frac{1}{27}\\
d-\log_{2}1=0\\
because\,\,2^0=1\\
e-\log_{10}\frac{1}{10}=-1\\
because\,\,10^{-1}=\frac{1}{10}\\
f-\log_{3}3=1\\
because\,\,3^1=3\\
g-\log_{2}2^k=k\\
because\,\,2^k=2^k
