Question

11. If x = 7+ 4√3 and xy = 1, then
x?​

Answer 1

Answer: 7- 4$\sqrt{3}$

I hope you are looking for value of y as x is already fixed value ie 7+4$\sqrt{3}$

Step-by-step explanation:

y will be 1/x , 1/(7+4$\sqrt{3}$) , rationalise by multiplying its conjugate.

(7-4$\sqrt{3}$)/(49-48) = 7- 4$\sqrt{3}$
