Answer:
B
Step-by-step explanation:
To rationalise the denominator.
Multiply the numerator/denominator by the radical on the denominator.
The radical on the denominator is [tex]\sqrt{11}[/tex], thus
Multiply the fraction by
[tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex] → B
The expression (√11 /√11 ) needs to be multiplied to rationalize the denominator.
Those numbers which can be written in the form p/q such that q > 0 ae called Rational Numbers.
The expression given is
( 2 √10) /( 3 √11 )
To rationalize the denominator , the radical √11 needs to be rationalize
( 2 √10) /( 3 √11 ) * (√11 /√11 )
(2√110) / 33
Therefore (√11 /√11 ) needs to be multiplied to rationalize the denominator.
