Question

Ok here is another one *ducks* dont shoot me! I cant help it that i suck at this stuff XD

Answer 1

Ok it says to multiply then simplify if possible, let me type it out now

Answer 2

\[\sqrt{10}(\sqrt{10}+z \sqrt{30})\]

Answer 3

\[\Large \sqrt{10}(\sqrt{10}+z\sqrt{30})\]



\[\Large \sqrt{10}\sqrt{10}+z\sqrt{10}\sqrt{30}\]



\[\Large \sqrt{10*10}+z\sqrt{10*30}\]



\[\Large \sqrt{100}+z\sqrt{300}\]



\[\Large \sqrt{100}+z\sqrt{100*3}\]



\[\Large \sqrt{100}+z\sqrt{100}*\sqrt{3}\]



\[\Large 10+z*10*\sqrt{3}\]



\[\Large 10+10z\sqrt{3}\]



So \[\Large \sqrt{10}(\sqrt{10}+z\sqrt{30})=10+10z\sqrt{3}\]

Answer 4

Thanks so much, your a life saver! :D How did you get the squared three though? that part lost me

Answer 5

\[\Large \sqrt{300}\]


\[\Large \sqrt{100*3}\]


\[\Large \sqrt{100}*\sqrt{3}\]


\[\Large 10\sqrt{3}\]



So \[\Large \sqrt{300}=10\sqrt{3}\]

Answer 6

So you just took the square of 300?

Answer 7

I simplified the square root of 300

Answer 8

taking the square root of 300 will give me a decimal number
