# Math Help - Rationalize each denominator

1. ## Rationalize each denominator

1/(√5)

&

(3t-1)/√(3t) -1)

2. Multiply top and bottom by sqrt(5). This is the same as multiplying by one, so it doesn't change the answer, just the way it looks. For example,
1/sqrt(2) can be rewritten as sqrt(2)/2 by multiplying the top and bottom of the fraction by sqrt(2).
