If `p,q in N" satisfy the equation "x^(sqrtx) = (sqrtx)^(x)`, thenA. p+q=5B. `|p-q|=4`C. pq=4D. if ` log_(q) p ` is defined, then ` log_(p)q ` is not and vice versa

Answer» Correct Answer - A::C::D
` x ^(sqrtx)=(sqrtx)^(x) ,p,qinN`
`rArr sqrtx log x = x log sqrtx`
` or log x [sqrtx - x/2] = 0`
` rArr log x = 0 or [sqrtx - x/2] = 0`
` rArr x = 1 or 4`
