Объяснение:
А2.
75₁₀ = 1*2⁰ + 1*2¹ + 0*2² + 1*2³ + 0*2⁴ + 0*2⁵ + 1*2⁶ = 1001011₂
A3.
607₁₀ = 15*16⁰ + 5*16¹ + 2*16² = 25F₁₆
A4.
1₁₀ = 1*5⁰ = 1₅
2₁₀ = 2*5⁰ = 2₅
3₁₀ = 3*5⁰ = 3₅
4₁₀ = 4*5⁰ = 4₅
5₁₀ = 0*5⁰ + 1*5¹ = 10₅
6₁₀ = 1*5⁰ + 1*5¹ = 11₅
7₁₀ = 2*5⁰ + 1*5¹ = 12₅
8₁₀ = 3*5⁰ + 1*5¹ = 13₅
9₁₀ = 4*5⁰ + 1*5¹ = 14₅
10₁₀ = 0*5⁰ + 2*5¹ = 20₅
A5.
1030₄ = 0*4⁰ + 3*4¹ + 0*4² + 1*4³ = 76₁₀
4E₁₆ = E*16⁰ + 4*16¹ = 78₁₀
B1.
A=110111₂ = 1*2⁰ + 1*2¹ + 1*2² + 0*2³ + 1*2⁴ + 1*2⁵ = 55₁₀
B=111₅ = 1*5⁰ + 1*5¹ + 1*5² = 31₁₀
C=53₈ = 3*8⁰ + 5*8¹ = 43₁₀
D=2E₁₆ = E*16⁰ + 2*16¹ = 46₁₀
B2.
111000,1₂ = 0*2⁰ + 0*2¹ + 0*2² + 1*2³ + 1*2⁴ + 1*2⁵ + 1/2¹ = 56,5₁₀
