Answer 1

Oie, tudo bom?

a)

$= 3 {}^{2} \: . \: 4 {}^{3} \\ = 9 \: . \: 64 \\ \boxed{ = 576⟶24 {}^{2} }$

b)

$= ( - 10 ){}^{3} \: . \: ( - 10) {}^{4} \: . \: ( - 10) {}^{2} \\ = ( - 10) {}^{3 + 4 + 2} \\ = ( - 10) {}^{9} \\ \boxed{ = - 10 {}^{9} }$

c)

$= ( - 12) \: . \: ( - 12) \: . \: ( - 12) {}^{2} \\ = ( - 12) {}^{1} \: . \: ( - 12) {}^{1} \: . \: ( - 12) {}^{2} \\ = ( - 12) {}^{1 + 1 + 2} \\ = ( - 12) {}^{4} \\ \boxed{ = 12 {}^{4} }$

d)

$= ( - 6) {}^{8} \div ( - 6) {}^{2} \\ = ( - 6) {}^{8 - 2} \\ = ( - 6) {}^{6} \\ \boxed{ = 6 {}^{6} }$

e)

$= 9 {}^{3} \div 9 \\ = 9 {}^{3} \div 9 {}^{1} \\ = 9 {}^{3 - 1} \\ \boxed{ = 9{}^{2} }$

f)

$= ( - 21) {}^{4} \div ( - 21) {}^{3} \\ = ( - 21) {}^{4 - 3} \\ = ( - 21) {}^{1} \\ \boxed{ = - 21}$
