Question

Differentiate the function
6/lnx

Answer 1

= -6/[x*(lnx)^2]

Answer 2

how did u get that?

Answer 3

You can use either quotient or chain rule.
If you want to use chain rule, you’d view it as 6 * (ln x)^(-1).
Then the derivative would be
6 * (-1) (ln x ) ^ (-2) * d/dx [ln x] = 6 (-1) (ln x) ^ (-2) * (1/x),

If you want to use the chain rule,
then you’d get (6*(1/x) – 0 * ln x)/ (ln x)^2,
which is the same thing as above.

Answer 4

thank u!
