Answer 1

Explicație pas cu pas:

$2 {}^{25} \div 2{}^{7} = 2 {}^{25 - 7} = 2 {}^{18} \\ 3 {}^{36} \div 3 {}^{9} = 3 {}^{36 - 9} = 3 {}^{ {}^{27} } \\ 5 {}^{40} \div 5 {}^{10 } = 5 {}^{40 - 10} = 5 {}^{30} \\ 6 {}^{36} \div 6 {}^{18} = 6 {}^{36 - 18} = 6 {}^{18} \\ 7 {}^{50} \div 7 {}^{22} = 7 {}^{50 - 22} = 7 {}^{28} \\ 9 {}^{49} \div 9 {}^{20} = 9 {}^{49 - 20 } = 9 {}^{29}$
