Question

What is the product of 5*sqrt(u)(sqrt(3) + sqrt(147)
5*sqrt(3u) + 7*sqrt(3)
40*sqrt(3u)
54*sqrt(3u)
35u*sqrt(3)

Answer 1

I have no idea at all, please help me with the answer!

Answer 2

\[5\sqrt{u}(\sqrt{3} +\sqrt{147})\]

Answer 3

that is your problem right??

Answer 4

Yes it is

Answer 5

\[=5\sqrt{u} ( \sqrt{3} + \sqrt{49 \times 3})\]\[=5\sqrt{u} ( 1\sqrt{3} + 7\sqrt{3})\]\[= 5\sqrt{u} ( 8\sqrt{3})\]\[= 40 \sqrt{u} \times \sqrt{3}\]\[= 40 \sqrt{3u}\]
