Question

Fie proportia
$\frac{5}{x} = \frac{3y}{5}$
Determinați valoarea expresiei
$(xy + 1 \frac{1}{2} )^{2}$
​

Answer 1

Răspuns:

Explicație pas cu pas:

5/x = 3y/5

3xy = 25

xy = 25/3

xy + 3/2 = 25/3 + 3/2 = 50/6 + 9/6 = 59/6

(59/6)^2 = 3481/36

Answer 2

5/x=3y/5 3xy=25 xy=25/3
xy+1+1/2=25/3+1+1/2=(50+6+3)/6=59/6
