Ex 13:
a) Mg = [tex]\sqrt{8 * 200 * 32}[/tex] = [tex]\sqrt{51200}[/tex]
Mg = 160*[tex]\sqrt{2}[/tex]
b) Mg = [tex]\sqrt{324 * 23 * 9}[/tex] = [tex]\sqrt{67068}[/tex]
Mg = 54*[tex]\sqrt{23}[/tex]
c) Mg = [tex]\sqrt{4 * 54 * ([tex]/sqrt{10}[/tex] - [tex]/sqrt{7}[/tex]) * ([tex]/sqrt{7}[/tex] + [tex]/sqrt{10}[/tex])[/tex] = [tex]\sqrt{67068}[/tex]
Mg = [tex]/sqrt{4 * 54 * (10 - 7)}[/tex] = [tex]/sqrt{4 * 54 * 3}[/tex] = [tex]/sqrt{648}[/tex] = 18*[tex]/sqrt{2}[/tex]
Succes!
