Question

(a,b,c) i.p. (2,3,4)

A,b,c = ?

dacă :
${a}^{2} + {b}^{2} + {c}^{2} = 976$
​

Answer 1

Răspuns:

a = 1/2 k

b = 1/3 k

c = 1/4 k

1/4 k ^2 + 1/9  k ^ 2 + 1/16 k ^2 = 976

k^2 x (1/4 + 1/9 + 1/16) = 976

k^2 x ( 36 + 16 + 9/144) = 976

k^2 x 61/144 = 976

k^2 x 61 = 976 x 144

k^ 2 = 16 x 144

k = 4 x 12

k= 48

a= 24

b= 16

c= 12
