a) 2⁴=... b)3⁰=...c)14²=... d)1³⁰=...e)14=...(2) f) 10111(2)=...​

Answer 1

Răspuns:

$a) \: {2}^{4} = 2 \times 2 \times 2 \times 2 = 16 \\ b) \: {3}^{0} = 1 \\ c) \: {14}^{2} = 14 \times 2 = 28 \\ d) \: {1}^{30} = 1 \\ e) \: 14 \div 2 = 7rest0 \\ 7 \div 2 = 3rest1 \\ 3 \div 2 = 1rest1 \\ f) 1110$

$1011 (2) = 1 \times {2}^{3} + 0 \times {2}^{2} + 1 \times {2}^{1} + 1 \times {2}^{0 } \\ 8 + 0 + 2 + 1 = \\ 11$
