00:01 Hello students here we have f x is equal to x4 e minus 9x so first we will calculate f dash x that is x cube e minus 9 x plus 4.
00:22 Now we will put f dash x is equal to 0 so 0 is equal to x cube e minus 9 x minus 9 x minus 9x plus 4.
00:36 So from here 0 is equal to minus 9x plus 4.
00:44 So 4 is equal to 9x and x is equal to 4 by 9...
