I have an algebra question that says i have to simplify the fraction by rationalizing the denominator of the fraction 4 sqrt 6/sqrt 30.

Question

problem is, idk what rationalizing is. well, i looked it up, but can someone help me rationalize the denominator of this fraction, then simplify? i received an answer yesterday, which was somewhat helpful, but when you answer, can you tell me what exactly you do to get the numbers you get?

Answer 1

again?
4√6/√30 * √30/√30 = 4√180/30 = 4*6√5/30 = 4√5/5
or
4√6/√30 = 4√6 / √5√6 = 4/√5 = 4√5/5

Answer 2

oh i see now thanks. i was confused yeterday.
