Question

Ma ajutati va rog. 1011²+221³=? (4)​

Answer 1

Răspuns:

300₍₄₎

Explicație pas cu pas:

10111₍₂₎ + 221₍₃₎ = ?₍₄₎

10111₍₂₎ = 1·2⁴+0·2³+1·2²+1·2¹+1·2⁰ = 16+0+4+2+1 = 23₍₁₀₎

221₍₃₎ = 2·3²+2·3¹+1·3⁰ = 18+6+1 = 25₍₁₀₎

23₍₁₀₎+25₍₁₀₎ = 48₍₁₀₎

48₍₁₀₎ = ?₍₄₎

48:4 = 12 rest 0

12:4 = 3 rest 0

3:4 = 0 rest 3  =>

48₍₁₀₎ = 300₍₄₎
