Answer 1

Step-by-step explanation:

(a).

${a}^{m} \times {b}^{m} = {(ab)}^{m}$

${(2a)}^{4} \times {(3b)}^{4} = {(2a \times 3b)}^{4}$

$= {(6ab)}^{4}$

(b).

${a}^{m} \times {a}^{n} = {a}^{m + n}$

$\frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n}$

SO,

$\frac{ {2}^{20} }{ {2}^{15} } \times {2}^{3}$

$= {2}^{20 - 15 + 3}$

$= {2}^{8}$
