What is the exact value of the expression the square root of 20. + the square root of 24. - the square root 54.? simplify if pos

aksik [14]

$\sqrt{20} = \sqrt{4} \sqrt{5} = 2 \sqrt{5}$
$\sqrt{24} = \sqrt{4} \sqrt{6} = 2 \sqrt{6}$
$\sqrt{54} = \sqrt{9} \sqrt{6} = 3 \sqrt{6}$

Because you can only add and subtract radicals with the same radicand,
you get 2 $\sqrt{5} - \sqrt{6}$
that is the simplified answer but if you want it in decimals, 2.022 is what you get.
