Va rog mai repede!Mersi

Answer 1

$1.M_{32}=[32\cdot1;32\cdot2;32\cdot3; 32\cdot4;32\cdot5]\\ \\ M_{32}=[32,64,96, 128, 160]$

2. cmmdc(714; 208)=?

cmmmc(714;208)=?

714 =2×3×7×17

208=2²×2²×13

cmmdc(714; 208)=2

cmmmc(714; 208)=2²×2²×3×7×13×17=74256

A={xIx∈N, 36<x<48}⇒

               A={37,38,39,40,41,42,43,44,45,46,47,48}

B ={ xIx∈N, 32<x<sau egal cu42}⇒

                  B={34,36,38,40,42}

A∪B={37,38,39,40,41,42,43,44,45,46,47,48}

A∩B={34,36,38,40,42}

A\B={37,39,41,43,44,45,46,47,48}

4.

11+3×[2+3(2×3-5)]-14=

11+3×[2+3(6-5)]-14=

11+3×[2+3×1]-14=

11+3×5-14=

11+15-14=

=26-14

=12
