Now, next solve the exercise 26.
00:04
In this exercise, we want to find the derivative of the function of x equals 5x to the power of 4 thirds, minus 2 thirds times x to a power of 3 halves, plus x squared minus 3x plus 1.
00:35
Know that according to rule 4, the derivative of the sum equals the sum of derivative, and hence it is just the sum of the derivative of each term.
00:53
It equals the derivative of the first term plus the derivative of a second term, plus the derivative of the third term, plus the derivative of a fourth term, and the derivative of the fifth term.
01:26
Now for the derivative of first term, we can first use rule 3.
01:34
So it equals a constant times as a derivative of function x to the power of fourth third.
01:44
And then, according to root 2, it equals 4 thirds time x to a power of 4 thirds minus 1, which is just 23rd times x to the power of 1 third.
02:08
And for the second term, it equals 2 thirds times the derivative of a function x to a power of 3 halves...
