5√3 is the correct answer. First you had to find the prime factorization of 75, and it gave us, $3*5^2=5*5=25*3=75$ , or $=\sqrt{5^2*3}$ . Then you can use apply radical rule, and it gave us, $\sqrt{3} \sqrt{5^2}$ , or $\sqrt{5^2}=5$ , and it gave us the answer is 5√3 is the correct answer. Hope this helps!
