Answer 2

Answer:

$\mathrm{Expand}\:\left(2\sqrt{a}+2\sqrt{b}\right)\cdot \:10:\quad 20\sqrt{a}+20\sqrt{b}$

Explanation:

$\left(2\sqrt{a}+2\sqrt{b}\right)\cdot \:10$

$=10\left(2\sqrt{a}+2\sqrt{b}\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac$

$a=10,\:b=2\sqrt{a},\:c=2\sqrt{b}$

$=10\cdot \:2\sqrt{a}+10\cdot \:2\sqrt{b}$

$\mathrm{Multiply\:the\:numbers:}\:10\cdot \:2=20$

$=20\sqrt{a}+20\sqrt{b}$
