a. 3x^(2)y^(3)√3:(3)

b. 9x^(3)y^(4)√3:(y)

c. 3x^(3)y^(6)√3:(3)

d. 3x^(3)y^(4)√3:(3y)

Rewrite it as:

√(3 *81X

^{6 }y^{9 )}=9√(3y) X^{3}y^{4} It should be written this way

(:) , you are using for Multiplication, it is a division sign. It should only use Fraction sign (/) for division.

The correct answer is be, and it should be written properly.
