Question

Calculati: b)(3/2+7/5+5/9)+(3/2+8/5+22/9)​

Answer 1

Răspuns: $\bf \red{ \underline{9}}$

Explicație pas cu pas:

$\bf \bigg( \dfrac{3}{2} + \dfrac{7}{5} + \dfrac{5}{9} \bigg) + \bigg( \dfrac{3}{2} + \dfrac{8}{5} + \dfrac{22}{9} \bigg) =$

$\bf \dfrac{3}{2} + \dfrac{7}{5} + \dfrac{5}{9} + \dfrac{3}{2} + \dfrac{8}{5} + \dfrac{22}{9} =$

$\bf \dfrac{3 + 3}{2} + \dfrac{7 + 8}{5} + \dfrac{5 + 22}{9} =$

$\bf \dfrac{6^{(2} \: }{2} + \dfrac{15^{(5} \: }{5} + \dfrac{27^{(9} \: }{9} =$

$\bf \dfrac{3 }{1} + \dfrac{3 }{1} + \dfrac{3 }{1} = 3 + 3 + 3 = \red{ \underline{9}}$
