how do i answer this?

Answer:
surds are option A, D and E
[tex]A. \ \sqrt{17} \\\\D. \ \sqrt{15} \\\\E. \ \sqrt{30}[/tex]
Step-by-step explanation:
Given;
[tex]A. \ \sqrt{17} \ \ \ \ B. \ \sqrt{36} \ \ \ \ C. \ \sqrt{100} \ \ \ \ D. \ \sqrt{15} \ \ \ \ E. \ \sqrt{30}[/tex]
A Surd have no perfect square root.
B. √36 = 6
C. √100 = 10
Option B and C have perfect square roots.
Thus, surds are option A, D and E, which have no perfect square root.
[tex]A. \ \sqrt{17} \\\\D. \ \sqrt{15} \\\\E. \ \sqrt{30}[/tex]
