If `(x+1/x)=3` , then `(x^2+1/(x^2))` is `(10)/3` (b) `(82)/9` (c) 7 (d) 11

If (x+(1)/(x))=3, then (x^(2)+(1)/(x^(2)))=?( a )7( b) 9(c)10(d)27

If (x-1)/(x)=3, then the value of 1+(1)/(x^(2)) is (a) 9(b) 10(c)11 (d) None of these

If x+(1)/(x)=2, then x^(3)+(1)/(x^(3))=64(b)14(c)8(d)2

If x=2+sqrt(3)3, then x^(3)+(1)/(x^(3))=2(b)4(c)8(d)9

If ( x- 3 )/5 - 2 = -1 , then x is equal to ( a ) 8 ( b) 3 ( c ) -7 ( d ) 2

If x=(2)/(3+sqrt(7)), then (x-3)^(2)=1 (b) 3 (c) 6( d) 7

If int(sqrt(1-x^(2)))/(x^(4))dx=A(x)*(sqrt(1-x^(2)))^(m) where A(x) is a function of x then (A(x))^(m)= (A) -(1)/(27x^(9))(B)(1)/((27x)^(9))(C)(1)/(3x^(9))(D)-(1)/(3x^(9))

If (3^(5x)x81^(2)x6561)/(3^(2x))=3^(7), then x=3 (b) -3(c)(1)/(3)(d)-(1)/(3)

If (2)/(2+(2)/(2+(2)/(x)))=3, then x is equal to -(4)/(7) (b) (4)/(7)(c)-(4)/(9)(d)(4)/(9)
