Answer:
[tex]\frac{2\sqrt{7} }{7}[/tex]
Step-by-step explanation:
Note that [tex]\sqrt{7}[/tex] × [tex]\sqrt{7}[/tex] = 7
Given
[tex]\frac{2}{\sqrt{7} }[/tex]
Rationalise the denominator by multiplying numerator/denominator by [tex]\sqrt{7}[/tex], that is
[tex]\frac{2}{\sqrt{7} }[/tex] × [tex]\frac{\sqrt{7} }{\sqrt{7} }[/tex]
= [tex]\frac{2\sqrt{7} }{7}[/tex]
