The correct option is (C)
What is expression?
An expression is a set of terms combined using the operations +, – , x or /.
Given expression:
[tex]\sqrt{7x^{2} }[/tex]÷ [tex]\sqrt{3x}[/tex]
Now, rationalise the denominator
[tex]\sqrt{7x^{2} }[/tex]/ [tex]\sqrt{3x}[/tex]* [tex]\sqrt{3x}[/tex]÷ [tex]\sqrt{3x}[/tex]
or, [tex]\sqrt{7x^{2} }[/tex] *[tex]\sqrt{3x}[/tex]/ [tex]{3x}[/tex]
or, [tex]\sqrt{7x^{2}* 3x }[/tex] /3x
or, √(21x³)/3x
or, √3*7*x³/3x
or, √3*7*x/3
or, √7x/√3
Hence, [tex]\sqrt{7x^{2} }[/tex]÷ [tex]\sqrt{3x}[/tex]= √7x/√3
