10

Write as : $\sqrt{4 \times 5} \times \sqrt{5}$ $sqrt(4xx5)xxsqrt(5)$

Giving: $\sqrt{4} \times \sqrt{5} \times \sqrt{5}$ $sqrt(4)xxsqrt(5)xxsqrt(5)$

$\Rightarrow 2 \times 5 = 10$ $=> 2xx5 = 10$

$10$ $10$

$\sqrt{a} \times \sqrt{b} = \sqrt{a b}$ $sqrtaxxsqrtb=sqrt(ab)$

(when $a, b \geq 0)$ $a,b>=0)$

Thus,

$\sqrt{20} \times \sqrt{5} = \sqrt{20 \times 5} = \sqrt{100} = 10$ $sqrt20xxsqrt5=sqrt(20xx5)=sqrt100=10$
