Please help me with these four question. I work them out,but I think I am doing something wrong.
+sqrt+%283.96%29+ = ± 1.989975
via calculator.
+sqrt+%280.32%29+
+sqrt+%280.48%29+
Use a calculator, or do you have some other question?
-----------
+sqrt%28324%29 + sqrt%28729%29 = 18 + 27 = 45 (principal value)
