Question

Simplify:
(i) $\sqrt{100} +\sqrt{36}$
(ii) $\sqrt{1360+9}$
(iii) $\sqrt{2704} +\sqrt{144} +\sqrt{289}$
(iv)$\sqrt{225} - \sqrt{25} ;$ (v) $\sqrt{1764} - \sqrt{1444} ;$(vi) $\sqrt{169} \times \sqrt{361} .$

Answer 1

i) $\sqrt{100} +\sqrt{36}$
$\implies 10 + 6$
$\implies 16$

(ii) $\sqrt{1360+9}$
$\implies \sqrt{1369}$
$\implies 37$

(iii) $\sqrt{2704} +\sqrt{144} +\sqrt{289}$
$\implies 52 + 12 + 17$
$\implies 81$

(iv)$\sqrt{225} - \sqrt{25}$
$\implies 15-5$
$\implies 10$

(v)$\sqrt{1764} - \sqrt{1444}$
$\implies 42-38$
$\implies 4$

(vi) $\sqrt{169} \times \sqrt{361}$
$\implies 13×19$
$\implies 247$
