Simplifying Radical Expressions

How do I do these? are there any simpler ways of simplifying these? wait let me put radical in my equation...

Answer 1

*\[\sqrt{125n}\] \[2\div \sqrt{5}\]

Answer 2

There, the first one is the radical expression and the 2nd one is the rationalizing the denominator one. Thanks.

Answer 3

in first what you do write 125 as 25*5 so you get Sqrroot(25*5*n) you can take out sqrroot of 25 as its a perfect square so your ans must be 5sqrroot(5n)
for second question just multiply both numerator and denominator by sqrroot(5)

Answer 4

Thanks bro!
