Question

Okay, help with simplifying square root expressions???

Answer 1

\[(6\sqrt{5})(2\sqrt{2})\] here's an example

Answer 2

\[\sqrt{x}=\sqrt{ab}=\sqrt{a}\sqrt{b}.\]

Answer 3

E.g.,\[\sqrt{56}=\sqrt{(4)(14)}=\sqrt{4}\sqrt{14}=2\sqrt{14}.\]

Answer 4

\[6\sqrt{5}=\sqrt{(36)(5)}=\sqrt{180}.\]

Answer 5

Get it?

Answer 6

I still don't get it. What's with the numbers before the square root symbols?

Answer 7

\[\sqrt{5}\]is just a number. You can multiply a number by another number, like\[2\sqrt{5}\]or\[1000\sqrt{5}\]

Answer 8

If i asked you to simplify\[\sqrt{4},\]you'd answer:\[2.\]

Answer 9

oh, ok. Thanks.

Answer 10

Notice, however, that\[\sqrt{a+b}\neq\sqrt{a}+\sqrt{b}\]as intuition would suggest.
