Using a calculator, work out \[ \frac{5.1 \times 10^{5}+1.4 \times 10^{4}}{3.5 \times 10^{-4}} \] Give your answer in standard form to 2 significant figures.

Step 1 ：Calculate the numerator: \(5.1 \times 10^{5} + 1.4 \times 10^{4} = 5.24 \times 10^{5}\)

Step 2 ：Divide the numerator by the denominator: \(\frac{5.24 \times 10^{5}}{3.5 \times 10^{-4}} = 1.50 \times 10^{9}\)

Step 3 ：\(\boxed{1.50 \times 10^{9}}\)
