$10^{3}$ $\times$ $10^{7}$ = 10$\times$10$\times$10$\times$10$\times$10$\times$10$\times$10$\times$10$\times$10$\times$10 = $10^{10}$ = $10^{3+7}$

#### Work Step by Step

The expression uses the exponents law for adding the exponents when the base is the same. $10^{3}$ $\times$ $10^{7}$ = $10^{3+7}$ = $10^{10}$
