If `x/2+x/5=28`, then x equals

If x+5=6 then x equals

If ( 2/3 )^(x - 1 ) = ( 3/2 )^(x-5 ) , then x is equal to :

If "log"_(x) (4x^("log"_(5)x) + 5) = 2 "log"_(5)x , then x equals to

5.If x<0,then |x| is equal to

If f(x)=|x^(2)-5x+6|, then f'(x) equals

If f(x) = (x - 1)/(4) + ((x - 1)^(2))/(12) + ((x -1)^(5))/(20) + ((x -1)^(7))/(28) + ... where 0 lt x lt 2 , then f'(x) is equal to

If A = ({:(5, 5x, x ),(0, x , 5x),(0, 0, 5):}) and |A^(2)| = 25 , then |x| is equal to

If log_(x)(4x^(log_(5)(x))+5)=2log_(5)x, then x equals to
