Pre-calc question about reciprocals! Please help!

[From: ] [author: ] [Date: 11-05-17] [Hit: ]
Just rationalize the denominator. Multiply 1/√3 by √(3)/√(3), which is the same thing as multiplying it by 1.Its just another form of writing the reciprocal. The reciprocal of 2 is 1/2, but you could also write it as 5/10 and its still equal.......
Why is it that the reciprocal of √3 is √(3)/3? Shouldn't it be like 1/√(3)? I don't understand this, and need to, can someone explain it?

1/√3 and √(3)/3 are equivalent. Just rationalize the denominator. Multiply 1/√3 by √(3)/√(3), which is the same thing as multiplying it by 1.

1/√(3) = 1/√(3) * √(3)/√(3) = √(3)/3

It's just another form of writing the reciprocal. The reciprocal of 2 is 1/2, but you could also write it as 5/10 and it's still equal.
