If x/(x^(1. 5)\ )=8x^(-1) and x >0, then x= (a) (sqrt(2))/4 (b) 2sqrt(2) (c) 4 (d) 64

If x/x^1.5=8x^-1 and x>0, then x= a. 2sqrt2 b. 4 c. 64 d. sqrt2/4

If x=5+2sqrt(6), then sqrt((x)/(2))-(1)/(sqrt(2x))= (a) 1 (b) 2 (c) 3 (d) 4

If x+\ sqrt(15)=4, then x+1/x= (a)2 (b) 4 (c) 8 (d) 1

If x=sqrt(5)+\ 2, then x-1/x equals (a) 2sqrt(5) (b) 4 (c) 2 (d) sqrt(5)

If x=sqrt(5)+2, then x-(1)/(x) equals 2sqrt(5)(b)4 (c) 2 (d) sqrt(5)

If x+sqrt(15)=4, then x+(1)/(x)=2(b)4(c)8 (d) 1
