Question

$a) (2 {}^{5} \times 2 { }^{6} \times 2 {}^{4} ) \: \div \: (2 {}^{7} \times 2 {}^{3} )$
$b)( \: 3 {}^{4} \div 3 {}^{3} ) \: \times \: (3 {}^{5} \div 3 {}^{3} )$
​

Answer 1

a)$a)2^{5} =32.  2^{6} =64 2^{4} =16\\32*64*16=32.768\\2^{3} =8 . 2^{7} =128\\128 *8=1.024\\32.768 / 1.024=32$

$b)3^{4} /3^{3} obviamente =3\\3^{5}/ 3^{3}= 3^{2}=9\\3*9=27$

Bons estudos
