Simplify the radical by rationalizing the denominator. Variables are assumed to be positive. 
square root sign over the following: 3x to the 6th power over 2y to the 4th power. The square root sign is over the whole fraction with a small 5 to the left of the square root sign. All to the 5th power.

[5th root of(3x^6/2y^4]^5

Note: [the 5th root of anything]^5 is just the "anything".
Are you sure that is what your problem calls for?????
