Question

calculeaza media geomatrica a nr a si b
a=radical 108 - radical 75
b=radical 147 + radical 192

Answer 1

$a= \sqrt{108} - \sqrt{75} =6 \sqrt{3} -5 \sqrt{3} = \sqrt{3} \\ b= \sqrt{147} + \sqrt{192} =7 \sqrt{3} +8 \sqrt{3} =15 \sqrt{3} \\ m_g= \sqrt{a*b} = \sqrt{ \sqrt{3} *15 \sqrt{3} } = \sqrt{15*3} = \sqrt{45} =3 \sqrt{5}$
