thank you!!^_^

Well, generally speaking you have:
Sqrt (a/b) x Sqrt (c/d)
you can multiply them to give Sqrt (ac/bd)
that can be written as Sqrt (ac) / Sqrt (bd) if ac or bd are nice numbers to take the square root from.
HOWEVER in the example you gave, both numbers are the same, so:
Sqrt (7/3) x Sqrt (7/3) = 7/3
as the square root of any number times itself gives you the non-square-rooted number.

Multiply both numbers and take the square root of the answer.
7/3 x 7/3 = 49/9
Square to get
49/9 = 7/3

â (7/3) * â (7/3) = â (7/3)^2 = 7/3

simple 7/3! cause it will be sqrt(49/9) [ i just multiplied the values IN THE RADICAL sign! so done!

[(7/3)^½] [(7/3)^½] = 7/3
Square roots are expressed equivalently in exponent of ½
(7/3)^(½ + ½) = (7/3)^(1) = 7/3

by definition of the sqr rt....if two intergers in sqr rt are multipled by to each other the answer is the integer itself
so the answer is 7/3

"Radical form" is totally irrelevant here.
If p is any number at all,
sqrt[p]*sqrt[p] = p.
It is the definition of sqrt[p].
