Question

Vă rog frumos rapid dau COROANĂ​

Answer 1

( 8rad3 + 14rad3 - 12rad 3 ) : rad75 =
( 10rad3 ) : rad75 =
rad 75 = 5rad3.

( 10rad3 ) / ( 5rad3 ) = 10/5 = 2. numar natural.

Answer 2

Răspuns:

A = 2

Explicație pas cu pas:

$A=(8\sqrt{3} +14\sqrt{3} -12\sqrt{3} ):\sqrt{75} \\\\\\A=(22\sqrt{3} -12\sqrt{3} ):5\sqrt{3}\\\\\\A=10\sqrt{3} :5\sqrt{3}\\\\\\\boxed{A=2}$
