$P$

$=$

$\{\sqrt{8}, \sqrt{14}, \sqrt{19}, \sqrt{23}, 3\}$ ,

$Q$

$=$

$\{\sqrt{14}, \sqrt{19}, 3, 8, 14\}$ and

$R$

$=$

$\{\sqrt{8}, \sqrt{14}, 3, 14, 23\}$ , then find the following:

(i)

$P - (Q \cap R)$

$=$

$\{\sqrt{i}, \sqrt{i}, \sqrt{i}\}$

(ii)

$P - Q$

$=$

$\{\sqrt{i}, \sqrt{i}\}$

(iii)

$P - R$

$=$

$\{\sqrt{i}, \sqrt{i}\}$

(iv)

$(P - Q) \cup (P - R)$

$=$

$\{\sqrt{i}, \sqrt{i}, \sqrt{i}\}$
