Answer

$2.3\times10^{3}$

Work Step by Step

$$\frac{6.9\times10^{8}}{3\times10^{5}}$$ Regroup like terms then simplify $$=(\frac{6.9}{3})(\frac{10^{8}}{10^{5}})$$ When dividing exponential expressions with the same non-zero base, subtract the exponent of the denominator from the exponent of the numerator. $$=2.3\times10^{(8-5)}$$ $$=2.3\times10^{3}$$
