Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\frac{dy}{dx}=$ Unnamed gap

Advice

Apply the rule:

$y=ax^n\,\,\,then\,\,\,\frac{dy}{dx}=nax^{n-1}$

In this example

$y=\var{a}x^{\var{b}}+\var{c}x^{\var{d}}+\var{f}$

$\frac{dy}{dx}=\var{b}*\var{a}x^{\var{b}-1}+\var{d}*\var{c}x^{\var{d}-1}$

$\frac{dy}{dx}=\simplify{{b}*{a}x^{{b}-1}+{d}*{c}x^{{d}-1}}$

Give a worked solution to the whole question.
