Question

radical din a ori 18 = 24

Answer 1

Răspuns:

cazul 1: a=16/9

cazul 2: a=32

Explicație pas cu pas:

$\sqrt{a} *18=24 => \sqrt{a} =\frac{24}{18} => \sqrt{a} =\frac{4}{3}$

acum ridicam la patrat

=> $\sqrt{a} ^{2} =(\frac{4}{3} )^{2} => a=\frac{4^{2} }{3^{2} } => a=\frac{16}{9}$

cazul 2:

$\sqrt{a*18} =24$

ridicam la patrat

$\sqrt{x*18} ^{2} =24^{2} => x*18=576 => x=\frac{576}{18}=32$
