Me ajudem por favor!!!!!​

Answer 1

Oie, Td Bom?!

a)

$= (x {}^{2} \: . \: x {}^{3} ) {}^{4}$

$= (x {}^{2 + 3} ) {}^{4}$

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

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

$= x {}^{20}$

b)

$= (x {}^{3} \: . \: x {}^{3} ) {}^{6}$

$= ( x{}^{3 + 3} ) {}^{6}$

$= (x {}^{6} ) {}^{6}$

$= x {}^{ 6 \: . \: 6}$

$= x {}^{36}$

c)

$= (x {}^{5} \div x {}^{3} ) {}^{4}$

$= (x {}^{5 - 3} ) {}^{4}$

$= ( {x}^{2} ) {}^{4}$

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

$= x {}^{8}$

d)

$= [(x {}^{2} \: . \: x {}^{3} )] {}^{2}$

$= [x {}^{2} \: . \: x {}^{3} ] {}^{2}$

$= [x {}^{2 + 3} ] {}^{2}$

$= [x {}^{5} ] {}^{2}$

$= x {}^{5 \: . \: 2}$

$= x {}^{10}$

e)

$= (x {}^{ - 4} \: . \: x {}^{5} ) {}^{4}$

$= ( x{}^{ - 4 + 5} ) {}^{4}$

$= (x {}^{1} ) {}^{4}$

$= x {}^{1 \: . \: 4}$

$= x {}^{4}$

f)

$= ( x{}^{ - 4} \: . \: x {}^{ - 6} ) {}^{ - 2}$

$= (x {}^{ - 4 + ( - 6)} ) {}^{ - 2}$

$= ( x{}^{ - 4 - 6} ) {}^{ - 2}$

$= (x {}^{ - 10} ) {}^{ - 2}$

$= x {}^{ - 10 \: . \: ( - 2)}$

$= x {}^{20}$
