Answer 2

Răspuns:

$a) {2}^{2} + {2}^{0} = \\ 4 + 1 = 5 \\ b) {3}^{3} - {5 }^{2} = \\ 27 - 25 = 2 \\ c)( {5}^{0} + {2}^{3} ) \div 3 = \\ (1 + 8) \div 3 = \\ 9 \div 3 = 3 \\ d) {2}^{7} - {3}^{0} - {11}^{2} = \\ 128 - 1 - 121 = \\ 127 - 121 = 6 \\ e) {9}^{2} - 5 \times {2}^{4} = \\ 81 - 5 \times 16 = \\ 81 - 80 = 1 \\ f) {8}^{2} - {7}^{2} = \\ 64 - 49 = 15 \\ l)( {7}^{0} + {2}^{3} ) \div {3}^{1} = \\ (1 + 8) \div 3 = \\ 9 \div 3 = 3$
