What is the square root of 75 to the nearest integer

kodGreya [7K]

<u><em>5√3 is the correct answer.</em></u> 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! And thank you for posting your question at here on brainly, and have a great day. -Charlie
