3sq root x - 4/sq root x = 4?

Question

3sq root x - 4/sq root x = 4?

Answer 1

3√x - 4/√x=4 → 3x - 4√x - 4 = 0



→ √x =( 4 + √(16 + 48)) / 6 → √x = 2  Ã¢Â†Â’ x= 4



check x=4 in the equation ;)

Answer 2

Square everything then then you have:

9x-(16/x) = 16

Muliply all sides by x

and simplify

you have

9xsquared - 16 = 16x

divide both sides by x

you have

9x = 16

divide both sides by 9

x= 16/9

Answer 3

3 sq root x-4/ sq root x = 4 Ha I don't think so try again!!!

Answer 4

3sq root x - 4/sq root x = 4

3sq root x  = 4 + 4/sq root x

3 = 4sq root x + 4sq root x/sq root x

3 = 4sq root x + 4

-1 = 4sq root x

-1/4 = sq root x

(-1/4)^2 = (sq root x)^2

1/16 = x

sq root 1/16 = +- 1/4

so,  3sq root x - 4/sq root x = 4, only  when x = 1/16
