Question

3 Square root of 5 multiplied by 2 with the square root of 4 equals

Answer 1

You don't understand I want to know how to work the problem. I don't get it!

Answer 2

9

Answer 3

Where did the other 3 come from?

Answer 4

\[3\sqrt5\times2\sqrt4=3\sqrt5\times2\times2=12\sqrt5\]

Answer 5

Okay I see now thank you

Answer 6

Note that it is not "3 to the power 5" @javo22

Answer 7

and @leahtripplethree I still have no idea what the hell "3 Square root of 5" means.

Answer 8

Therefore I am just guessing.

Answer 9

"3 square root of 5" if written

\[3\sqrt{5} = 3 * \sqrt{5}\]

Now, if you saw this:
\[\sqrt[3]{5}\]that means the 3rd (or cube) root of 5: a number that when multiplied with itself twice = 5. For example, \[\sqrt[3]{8} = 2\]because \[2*2*2 = 8\]

Answer 10

Therefore the question is ambiguous.

Answer 11

However I reckon that it is \(3\sqrt5\) since one would not write \(\sqrt[2]4\).

Answer 12

no, the problem isn't ambiguous if we see it accurately. Hearing your description of what it looks like on the paper, however, is a different story.

Answer 13

Without knowing whether you are aware of how a cube root might be notated, we can't really be sure which of the two is meant, but I agree that \(3\sqrt{5}\) is more likely because you get an answer that reflects actual useful manipulation, unlike with the cube root where all that is reflected is the ability to figure out the square root of 4 :-)

Answer 14

sorry, @kc_kennylau I said "your description" but was referring to the original poster's description, of course!

Answer 15
