exercitii de clasa 8 la matematica
Se dau exercitii 108si 54
b)Scristi cite 5 elementeale multimilor M108,M54.
d)Determinati c.m.m.m.c.al numerelor 108 si 54.

Answer 1

b)$M_{108} =0,108,216,324,432,540...$
$M_{54}=0,54,108,162,216,...$
d)$108= 2^{2}x 3^{3}$
$54=2x 3^{3}$
c.m.m.m.c.(108,54)=$2^{2} x 3^{3} =108$

Answer 2

a. M108=[0,108,216,324,432];
b. M54=[0,54,108,216,324];
c. 108=2²·3³⇒descompunere in factori primi;
54=2·3³;
⇒c.m.m.m.c=2²·3³=4·27=108;
