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

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

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 ў 8 = 0.625
