$$1.31\times 10^{12} .$$
We use the exponent rules to simplify the fraction as follows: $$\frac{\sqrt{6.05\times 10^{9}}}{(244\times 10^{-6})^{2}}=\frac{\sqrt{60.5\times 10^{8}}}{(244\times 10^{-6})^{2}}\\=\frac{ 7.778\times 10^{4}}{59536\times 10^{-12}} =0.00013064\times 10^{16}\\=1.306\times 10^{16-4}=1.31\times 10^{12} .$$
