Question

A rationalising factor of ³√25+(1/³√25)-1 is

​

Answer 1

Answer:

The simplest rationalising factor is that number, when we multiply ..we get the simplest rational number..

so, √5 is the rationalising factor of ³√25

bcoz when we multiply both of them.we get ³√125 =³√5³=5

As same so

5+1/5-1

=5/1+1/5-1/1

25+1-5/5

=19/5

=3.8
