Question

when the denominator of 1/2root 5 is rationalized it becomes root k/10 find k​

Answer 1

When a radical contains an expression that is not a perfect root, for example, the square root of 3 or cube root of 5, it is called an irrational number. So, in order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.
