Answer 1

2. b) 81-64 = 17 c) 125 + 243 = 368 d) 32-25 = 7 e) 128+49 = 177 f) 81-81 = 0 g) 8+4+2+1 = 15 h) 3^9 - (3^3)^3 = 3^9 - 3^9 = 0 ^ → inseamna la puterea 3. a) 9+1-1+16 = 25 b) 121-11+1 = 111 c) 25-32+1 = -6  d) 0+13+1 = 14 e) (23-9-1)² - 13² = 13² - 13² = 0

Answer 2

$2) \\ \\ {2}^{2} + {3}^{3} = 4 + 27 = 31 \\ \\ {3}^{4} - {4}^{3} = 81 - 64 = 17 \\ \\ {5}^{3} + {3}^{5} = 125 + 243 = 368 \\ \\ {2}^{5} - {5}^{2} = 32 - 25 = 7 \\ \\ {2}^{7} + {7}^{2} = 128 + 49 = 177 \\ \\ {3}^{4} - {9}^{2} = 81 - 81 = 0 \\ \\ {2}^{3} + {2}^{2} + {2}^{1} + {2}^{0} = 8 + 4 + 2 + 1 = 15 \\ \\ {3}^{9} - {27}^{3} = 19683 - 19683 = 0 \\ \\ 3) \\ \\ {3}^{2} + {13}^{0} - {1}^{10} + {4}^{2} = 9 + 1 - 1 + 16 = 9 + 16 = 25 \\ \\ {11}^{2} - {11}^{1} + {11}^{0} = 121 - 11 + 1 = 111 \\ \\ {5}^{2} - {2}^{5} + {19}^{0} = 25 - 32 + 1 = - 6 \\ \\ {0}^{13} + {13}^{1} + {13}^{0} = 0 + 13 + 1 = 14 \\ \\ (23 - {3}^{2} - {23}^{0}) ^{2} - {13}^{2} = (23 - 9 - 1) ^{2} - {13}^{2} = {13}^{2} - {13}^{2} = 169 - 169 = 0$
