Please help me find the answer to this problem. it would be nice to have the details to how you came by the answer:

Radical of 3/4 + radical of 1/3

your help is greatly appreciated

Assuming you use consistent syntax, I'll assume you have

√(3/4) + √(1/3)

√(3/4) = √3/√4 = √3/2
√(1/3) = √1/√3 = √3/3

So, you have √3/2 + √3/3 = 5√3/6
or,
5/6 * √3
or,
5/(2√3)
