Answer:

The answer is
3^(7)√(3) ⇒ answer (d)

Explanation:

* How to simplify the square root

- The square is even root ⇒ because 2 is an even number

- We can'f find square root for negative number,

- we can change the square root by rational exponent 1/2

* Lets look to our problem

- We have √(3^15)

- That means √(3^14 × 3)

- Lets change the square root to √3 to (3)^1/2


\sqrt{3^(15)}=\sqrt{3^(14)(3)}=(3^(14))^{(1)/(2)}(3)^{(1)/(2)}

∵ 14 × 1/2 = 7

∵ 3^1/2 = √3


3^(7)(3^{(1)/(2)})=3^(7)√(3)

∴ The answer is (d)
