The answer will depend on whether the original function is 2/x9 or (2/x)9 but the difference is only in the coefficient.
In the first case the derivative is -18/x10 and in the second it is -4608/x10.

9
the reciprocal of 2 over 9 is 9 over 2
2/9 + 2/3 = 2/9 + 6/9 = 8/9
The answer to the mathematical equation of what is 9 times 2 over 9 is 2.
2/9 + 4/9 = 6/9 6/9 in its simplest form is 2/3
d/dx (x2+ 9)1/2= 1/2*(x2+ 9)-1/22x = x(x2+ 9)-1/2or x/(x2+ 9)1/2
2/3 = 6/9 2/9 + 6/9 = 8/9
2/9 + 5/9 = 7/9
2 over 7.
2 over 9 as a decimal = 0.2222 2/9: = 2 ÷ 9 = 0.2222 in decimal
2 over 9 or 2/9 is already in its simplest form.
