(ii) 1.3 ×109

Answer 1

$$\begin{gathered} \left(1\right). \\ \left(\mathrm{a}\right)782000000=7.82\times {10}^8 \\ \left(\mathrm{b}\right)609.99=6.0999\times {10}^2 \\ \left(\mathrm{c}\right).0.234\times {10}^5=2.34\times {10}^4 \\ \left(\mathrm{d}\right)5\mathrm{million}=5000000=5\times {10}^6 \\ \left(2\right). \\ \left(\mathrm{a}\right)9.876\times {10}^6=9876000 \\ \left(\mathrm{b}\right).1.3\times {10}^9=1300000000 \end{gathered}$$
