if 3 times the square root of 7 divided by "a" times the square root of 7 equals 3 times the sqaure root of 7 divided by 7 is true then a must equal?
---------------------------------------
(3sqrt(7)]/[a*(sqrt(7)] = [3sqrt(7)]/7
-----
Cross-multiply to get:
21sqrt(7) = 3a*sqrt(7)
----
Divide both sides by 3*sqrt(7) to get:
7 = a
