$=$

$\sqrt{i}$

(ii)

$\sqrt{35} \div \sqrt{7}$

$=$

$\sqrt{i}$

$\sqrt[3]{27} \times \sqrt[3]{8} \times \sqrt[3]{125}$

$=$

$i$

(iv)

$(7 \sqrt{a} - 5 \sqrt{b}) (7 \sqrt{a} + 5 \sqrt{b})$

$=$

$i a - i b$

(v)

$[\sqrt{\frac{225}{729}} - \sqrt{\frac{25}{144}}] \div \sqrt{\frac{16}{81}}$

$=$

$\frac{i}{i}$
