Answer:

Both C & D are correct

Explanation:


v^(2) =(25)/(81)

Root both sides of the equation to remove the square.


v=\±\sqrt{(25)/(81) }


v = \±\sqrt{(5*5)/(9*9) } \\v=\±(5)/(9)

Therefore,


v=\sqrt{(25)/(81) } =-\sqrt{(25)/(81) }

Answer: Both C and D are correct

Explanation:

To remove the exponent from the v you need to square root both sides,

the exponent on the v is then canceled out giving you:


v=√(25/81) or
v=-√(25/81)
