I taught John Birt, former Director of the BBC in 1961. His homework book was the most perfect I have ever marked. And also the most neat. I could tell he was destined for great things.
One of my classmates was the poet Roger McGough, and I have a mention in his autobiography.

Question
my problems (set 2):
For Exercises 9 and 10 find the derivative of each expression and simplify.
9. (1/a)((1/b)(x²)-(2/a)(x)-(d/x))
10. (-8x^-8)+(12√x)
Answer
Hello Asad
You don't say what to differentiate with respect to, but I shall assume it is x.
9. (1/a)(2x/b - 2/a + d/x^2). It is arguable what the simplest expression is here.
It may be 2x/(ab) - 2/a^2 + d/(ax^2), or an expression with common denominator.
The one I give is best for eg. differentiating again.
10. 64x^(-9) + 6x^(-1/2) = 64/x^9 + 6/√x
Best wishes
