Answer 1

Oie, Td Bom?!

a)

$= 4 {}^{3} \: . \: 4 \: . \: 4 {}^{2}$

$= 4 {}^{3} \: . \: 4 {}^{1} \: . \: 4 {}^{2}$

$= 4 {}^{3 + 1 + 2}$

$= 4 {}^{3 + 3}$

$= 4 {}^{6}$

b)

$= 5 {}^{9} \div 5 {}^{3}$

$= 5 {}^{9 - 3}$

$= 5 {}^{6}$

c)

$= 8 {}^{4} \div 8 {}^{0}$

$= 8 {}^{4} \div 1$

$= 8 {}^{4}$

d)

$= (4 {}^{4} ) {}^{5}$

$= 4 {}^{4 \: . \: 5}$

$= 4 {}^{20}$
