10. Solve each radical expression. Check your solution.
1=√(2v3)
11. Solve each radical expression. Check your solution.
√(n+5)= √(5n11)
12. Tell which solutions, if any, are extraneous for each question.
√(12n)=n;
n= 4,n=3

#10. since 1=√1, you must have 2v3 = 1
#11.
√(n+5)= √(5n11)
n+5 = 5n11
n = 4
check: √9 = √9
#12. well, geez, just check them!
√(12(4)) = √(12+4) = √16 = 4 Since this is not equal to 4, that value is extraneous.
√(123) = √9 = 3
yep, that one is ok.
