$$Sorry, for clarification, the problems would be \sqrt{g4y ^{10}}h ^{5}/16y^12h^3 for question 1$$

anonymous · Answer

And $$\sqrt{7} + 3 \sqrt{7}$$ For question 2

usukidoll · Answer

for number 2 combine like terms.. clearly you have square roots of 7 so just add them up....

usukidoll · Answer

ok to make it easier factor out the square root of 7 and then add 1 + 3.. what do you get?

usukidoll · Answer

|dw:1398940353010:dw|

anonymous · Answer

uhh $$2\sqrt{7}$$

usukidoll · Answer

no what is 3 + 1

anonymous · Answer

Oh, just 3+1? that's 4... Right?.. This isn't some sort of joke question?
