if 1/(6!)+1/(7!)=x/(8!) , then x is ……

The value of the integral int_(0)^(1) x(1 - x)^(5)dx is equal to a) (1)/(6) b) (1)/(7) c) (6)/(7) d) (1)/(42)

If in a binomial distribution n=4,P(X=0)=(16)/(81), then P(X=4) equals (1)/(16) b.(1)/(81) c.(1)/(27) d.(1)/(8)

If log_(x)((9)/(16))=-(1)/(2), then x is equal to a.-(3)/(4) b.(3)/(4) c.(81)/(256)d.(256)/(81)

If x^((1)/(4)) + x^((-1)/(4))=2 , then what is the value of x^(81) + ((1)/(x^(81))) ?

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

If x = sqrt7 + sqrt6 , then find the simpliest value of (a) x - (1)/(x) , (b) x + (1)/(x) , (c) x^(2) + (1)/(x^(2)) , (d) x^(3) + (1)/(x^(3))

(1)/(6x - 7 - x^(2))

(1)/(7+6x-x^(2))
