How do I solve Radical square root.
Such as 11 times the square root of 196 divided by 9 times the square root of 256

Is it
11√196/(9√256)
or
11√196/9 *√256
anyway √196 = 14 and √256 = 16
I am sure you can do the rest

11ã196

9ã256
I know to do the square roots. I come up with
154

144
My problem is what to do now. Do I divide? And do I need to simplify because it is a radical?

so it reduces to 77/72 or 1 5/72

So the line doesn't stand for division?

of course it does.
any fraction is really a division of the numerator by the denominator
e.g. 5/8 = 5 ÷ 8 = 0.625
