It seems like ages ago – but it was only yesterday – that I wrote about differentiating functions with the variable in both the base and the power.

Here in ×îÐÂÌÇÐÄVlog, we are at the tail end of a reality cooking competition called "". In the show, a group of hopefuls compete in challenges where they produce desserts, hosted by patissier Adriano Zumbo. There are two types of challenges. In the "Sweet Sensations" challenge, they have to create a dessert from scratch that matches a criterion such as "gravity-defying", "showcasing one colour" or "based on an Arnott's biscuit".

In this test, Zumbo reveals a dessert he has designed and the two contestants try to recreate it. Whoever does the worst job is eliminated.
