calculati media geometrica a numerelor: a=radical 75 + Radical 48- Radical 12 SI b =radical 108 + radical 147 + Radical 192

mg = a*b
mg = [tex]( \sqrt{75}+ \sqrt{48}- \sqrt{12})( \sqrt{108} + \sqrt{147} + \sqrt{192})= [/tex][tex] \sqrt{8100}+ \sqrt{11025} +\sqrt{5184} + \sqrt{7056}+ \sqrt{9216}- \sqrt{1296} \sqrt{1764}- \sqrt{2304} [/tex]=90+105+72+84+96-36-42-48=321
