Răspuns:
cazul 1: a=16/9
cazul 2: a=32
Explicație pas cu pas:
[tex]\sqrt{a} *18=24 => \sqrt{a} =\frac{24}{18} => \sqrt{a} =\frac{4}{3}[/tex]
acum ridicam la patrat
=> [tex]\sqrt{a} ^{2} =(\frac{4}{3} )^{2} => a=\frac{4^{2} }{3^{2} } => a=\frac{16}{9}[/tex]
cazul 2:
[tex]\sqrt{a*18} =24[/tex]
ridicam la patrat
[tex]\sqrt{x*18} ^{2} =24^{2} => x*18=576 => x=\frac{576}{18}=32[/tex]
