Answer 1

Răspuns:

$a)22 \times 2 \div 11 = 44 \div 11 = 4 \\ b)360 \div 10 \times 6 = 36 \times 6 = 216 \\ c) {3}^{2} \times 8 \div 12 \times 13 \div 39 = 9 \times 8 \div 12 \times 13 \div 39 = 72 \div 12 \times 13 \div 39 = 6 \times 13 \div 39 = 78 \div 39 = 2 \\ d)5 \times 12 \times 17 \div 255 = 60 \times 17 \div 255 = 1020 \div 255 = 4 \\ e)12 \times 11 \div 44 \times 16 \div 24 = 132 \div 44 \times 16 \div 24 = 3 \times 16 \div 24 = 48 \div 24 = 2 \\ f)456 \div 24 \times {5}^{2} \div 19 \times 20 = 19 \times 25 \div 19 \times 20 = 475 \div 19 \times 20 = 25 \times 20 = 500$
