Question

derivativate (sqrt16-x)

Answer 1

\[\sqrt{16-x}\]

Answer 2

is it (16-x)^2

Answer 3

first you use the chain rule so take the derivative of 16-x, that is just -1
than multiply -1 with the derivative of the sqrt that is 1/2 * (16-x)^(-1/2)

so the solution is:
- 1/2 (16-x)^(-1/2)= -1/ (2 sqrt(16-x))

Answer 4

when there is a polynomial like x^n than the derivative will be: n*x^(n-1)

Answer 5

o ok cool thanks

Answer 6

so here the sqrt mean 1/2
so sqrt x= x^1/2

Answer 7

ok thanks : )

Answer 8

no problem :-)
