Question

Aratati ca nr.sunt cuburi de nr.nat.
a=3 la puterea 2 X 3 la putere 0+2 la puterea 3+2 X 5
b=2 X 3 la puterea 2+ 3 la putere 2
c=10 la putere 2 X 10 la putere o+ 10 la puterea 2 X 2+10 la putere 2 X 3+10 la puterea 2 X 4

Answer 1

a=3² X 3⁰+2³+2 X 5=3² +2(2²+ 5)=3² +2x3²=3²(1+2)=3²x3=3³
b=2 X 3²+ 3²=3²(2+1)=3²x3=3³
c=10²X10⁰+ 10² X 2+10² X 3+10² X 4=10²(1+ 2+ 3+ 4)=10² X10=10³
