sqrt{5a}+3sqrt{125a^{3}}

anonymous · Answer

grr it wont post it right XD

$$\sqrt{5a}+3\sqrt{125a^{3}} $$

anonymous · Answer

$$125=5^3$$ so you get 
$$\sqrt{5a}+15a\sqrt{5a}$$
to combine write 
$$(1+15a)\sqrt{5a}$$

anonymous · Answer

I got $$15\sqrt{5a}$$ but I have and icky feeling Im wrong
