Question

rationalize the denominator and simplify
squre root of 121/5

Answer 1

11sqrt5/5

Answer 2

y ? i know 11 comes out twice so its taken out of the sqrt then five remains on the bottom how does it get to the top? gosh im confusing myself

Answer 3

you will have a square root of 5 on the bottom. In order to get rid of that you multiply the top and bottom by square root of 5. resulting in dhatraditya's answer

Answer 4

if you multiply a square root by a square root you will cancel the roots and just end up with the number.. so sq root of 5 x sq root of 5 = 5
