Answer 1

a)
$a \times b = {2}^{3} \times {2}^{2} = {2}^{3 + 2} = {2}^{5} = 32$

b)
$a \times c = {2}^{3} \times {2}^{ - 3} = {2}^{3 - 3} = {2}^{0} = 1$

c)
$b \times c = {2}^{2} \times {2}^{ - 3} = {2}^{2 - 3} = {2}^{ - 1} = \frac{1}{2}$

d)
$a \times b \times c = {2}^{5} \times {2}^{ - 3} = {2}^{5 - 3} = {2}^{2} = 4$
