Answer:
(2√5+5)/5
Step-by-step explanation:
Given that,
(2+√5)/√5
consider denominator
⇒√5
to rationalise it we should multiply it with '√5'
so,
divide and multiply by √5 with numerator & denominator
⇒(2+√5)/√5 × √5/√5
⇒(2+√5)(√5)/(√5)(√5)
⇒(2√5+5)/5 (∵(a+b)c=ac+bc)
∴ rationalisation of the denominator of 2+√5/√5 = (2√5+5)/5
