$a) {9}^{8} \times {9}^{3} = {9}^{8 + 3} = {9}^{11}$

$b) {31}^{24} \times {31}^{78} = {31}^{24 + 78} = {31}^{102}$

$c) {4}^{25} \times 4 = {4}^{25 + 1} = {4}^{26}$

$d)52 \times {52}^{8} = {52}^{1 + 8} = {52}^{9}$

$e) {10}^{5} \times {10}^{6} \times {10}^{7} = {10}^{5 + 6 + 7} = {10}^{18}$

$f) {a}^{2} \times {a}^{7} = {a}^{2 + 7} = {a}^{9}$

$g) {n}^{3} \times n \times {n}^{2} = {n}^{3 + 1 + 2} = {n}^{6}$

$h) {c}^{d} \times c = {c}^{d + 1}$
