Answer 1

Răspuns:

$2 {}^{5} - 3 = 32 - 3 = 29$

$5 {}^{2} + {2}^{2} = 25 + 4 = 29$

$7 {}^{3} + 6 {}^{2} = 343 + 36 = 379$

$2 {}^{3} \times 2 {}^{3} = 2 {}^{3 + 3} = 2 {}^{6}$

$32 {}^{1} + 32 {}^{0} = 32 + 1 = 33$

$1 {}^{36} + 0 {}^{42} + 2016 {}^{1} = 1 + 0 + 2016 = 2017$

$2 {}^{6} + 2 = 64 + 2 = 66$

$3 {}^{4} - 2 {}^{4} = 81 - 16 = 65$

$3 {}^{3} - 2 {}^{3} = 27 - 8 = 19$

$3 {}^{2} \div 3 = 3 {}^{2} \div 3 {}^{1} = 3 {}^{2 - 1} = 3 {}^{1} = 3$

$10 {}^{4} - 5 {}^{5} = (2 \times 5) {}^{4} - 5 {}^{5} = 2 {}^{4} \times 5 {}^{4} - 5 {}^{5} = (2 {}^{4} - 5) \times 5 {}^{4} = (16 - 5) \times 625 = 11 \times 625 = 6875$
