Question

Vă rog frumos, am nevoie urgent de rezolvare! ​

Answer 1

Salut.

a)

|x-2|≤50

-50≤x-2≤50

-48≤x≤52

x∈[-48,52]

M=A∩Z=[-48,52]

b)

de la -48 pana la 52 sunt ...48(-48 pana la -1)+1(0)+52(1 pana la 52)=101nr

cardinalul multimii M=101

c)

-48-47-46-...-1+0+1+2+...+52=49+50+51+52=100+102=202

(-48)*(-47)*...*(-1)*0*1*...*52=0
