ofx.

Answer 1

Answer:

don't know but mark me as brainlist

Answer 2

$log_{10}(y) + log_{10}(x) = 2$

We know that;

$\color{blue}{ \boxed{ log(x) + log(y) = log(xy) }}$

$\implies \: log_{10}(xy) = 2$

We also know that;

If,

$\color{blue} log_{a}(N) = x$

Then:

$\color{blue}{ N} = {a}^{x}$

$\implies xy={10}^{2}$

$\implies xy = 100$

${ \boxed{\color{orange} \therefore y = \frac{100}{x} }}$

HOPE THAT HELPS!!
