Question

Помооогитеееее плиииз!!!!

Answer 1

$1) 36x^2-4=0$
$36x^2=4$
$x^2= frac{1}{9}$
$x=+- frac{1}{3}$
$x= frac{1}{3} ; x=- frac{1}{3}$

$3) sqrt{x-5} = sqrt{3-x} ;$
$x-5=3-x$
$x+x=3+5$
$2x=8$
$x=4$
$sqrt{4-5} = sqrt{3-4}$
$sqrt{-1} = sqrt{-1}$
$x neq 4$
x∈∅

$4) frac{3x+27y}{9 x y}$
$frac{3(x+9y)}{9xy}$
$frac{x+9y}{3xy}$

$5) frac{t}{t-2} + frac{2}{2-t}$
$frac{t}{t-2} + frac{2}{-(t-2)}$
$frac{t-2}{t-2}$
$1$
