Answer 1

a)$14 {}^{5} \div 7 {}^{5} = (2 \times 7) {}^{5} \div 7 {}^{5} = 2 {}^{5} \times 7 {}^{5} \div 7 {}^{5} = 2 {}^{5} = 2 \times 2 \times 2 \times 2 \times 2$
b) $24 {}^{8} \div 8 {}^{8} = (3 \times 8) {}^{8} \div 8 {}^{8} = 3 {}^{8} \times 8 {}^{8} \div 8 {}^{8} = 3 {}^{8} = 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3$
c) $100 {}^{50} \div 20 {}^{50} = (20 \times 5) {}^{50} \div 20 {}^{50} = 20 {}^{50} \times 5 {}^{50} \div 20 {}^{50} = 5 {}^{50} = 5 \times 5 \times ... \times 5$ de 50 de ori
