Answer 1

a) $4^{31} = (2^{2})^{31} = 2^{62}$

$8^{21} = (2^{3})^{21} = 2^{63}$

$16^{15} = (2^{4})^{15} = 2^{60}$

$=> 16^{15}, 4^{31}, 8^{21}.$

b) $27^{13} = 3^{39}$

$9^{18} = 3^{36}$

$=> 9^{18}, 3^{37}, 27^{13}.$

c) $8^{17} = 2^{51}$

$32^{10} = 2^{50}$

$=> 2^{48}, 32^{10}, 8^{17}.$

d) $81^{11}=3^{44}$

$9^{21}=3^{42}$

$=> 3^{41}, 9^{21}, 81^{11}.$
