text: determine the derivative? determine the derivative of f(x) (6 with only x under the square root sign -2)(5 with only x under the square root sign +7) do u mean 1) [6(x)^-2]*[5(x)^7]   ? or 2) [6(x)^-2] , 3) [5(x)^7]  then the ans is 1) -150(x)^-6.....                           2) -12(x)^-3                            3) 35(x)^6
