Question

Scrieți numerele naturale ce au următoarele descompuneri:

a) 3×10³+9×10²+2;
b) 1×10la puterea 4 +2×10³+3×10²+4×10+7;
c) 5×10³+4×10+8;
d) 6×10la puterea 5 + 8×10³-10²+9;

Va rog ajutatima rapidddd​

Answer 1

a.3*10³+9*10²+2=3*1000+9*100+3=3000+900+3=3903

b.1*10⁴+2*10³+3*10²+4*10+7=10⁴+2*10³+3*10²+47

=10000+2*1000+3*100+47

=10000+2000+300+47=12347

c.5*10³+4*10+8=5*1000+40+8=5000+40+8=5048

d.6*10⁵+8*10³-10²+9=6*100000+8*1000-100+9

=600000+8000-100+9=607909
