Answer 1

$a) {a}^{3} \times a = {a}^{3 + 1} = {a}^{4} \\ g) {x}^{0} \times {x}^{4} = {x}^{0 + 4} = {x}^{4} \\ j) {x}^{4} {y}^{5} \times xy = {x}^{4 + 1} \times {y}^{5 + 1} = {x}^{5} {y}^{6}$

$b) {a}^{5} \times {a}^{7} = {a}^{5 + 7} = {a}^{12} \\ d)a {b}^{2} \times {a}^{2}b = {a}^{1 + 2} \times {b}^{2 + 1} = {a}^{3} {b}^{3} \\ z) {x}^{0} {y}^{10} \times {x}^{0} {y}^{3} = {x}^{0 + 0} \times {y}^{10 + 3} = {x}^{0} \times {y}^{13} = 1 \times {y}^{13} = {y}^{13}$

$v){x}^{10} \times {x}^{10} = {x}^{10 + 10} = {x}^{20} \\ e) {a}^{2} {b}^{3} \times {a}^{5} {b}^{7} = {a}^{2 + 5} \times {b}^{3 + 7} = {a}^{7} {b}^{10}$
