Answer 1

Răspuns:

11=1×2¹+1×2⁰=1×2+1×1=2+1=3

1010=1×2³+0×2²+1×2¹+0×2⁰=1×8+0×4+1×2+0×1=8+0+2+0=10

111000=1×2⁵+1×2⁴+1×2³+0×2²+0×2¹+0×2⁰=1×32+1×16+1×8+0×4+0×2+0×1=32+16+8+0+0+0=56

1000001=1×2⁶+0×2⁵+0×2⁴+0×2³+0×2²+0×2¹+1×2⁰=1×64+0×32+0×16+0×8+0×4+0×2+1×1=64+0+0+0+0+0+1=65

10101011=1×2⁷+0×2⁶+1×2⁵+0×2⁴+1×2³+0×2²+1×2¹+1×2⁰=1×128+0×64+1×32+0×16+1×8+0×4+1×2+1×1=128+0+32+0+8+0+2+1=171.
