TutorWhich is bigger, 2¹⁰⁰ or 3⁶⁰?
YouBoth are huge. I could take logs, but I don't know log 3 well enough.
Hint100 and 60 are both multiples of 20.
YouOh, so 2¹⁰⁰ = 32²⁰ and 3⁶⁰ = 27²⁰. 32 is bigger than 27, so 2¹⁰⁰ wins. Check: 2⁵ = 32 and 3³ = 27. Yes.

What the universities say
Mia's feedback rewards what their own pages describe: thinking aloud, working with hints, and fixing mistakes.
“You may be asked to explore unfamiliar ideas, think through problems aloud or consider new perspectives.”
University of Oxford: Interviews“Students do make mistakes, and that's fine”
“It's not assumed that a less-talented student will need more help on any given problem”
University of Oxford: Sample interview questions“we may ask you to solve a problem and talk us through your thought processes”
Oxford Mathematical Institute: Interviews“Our tutors are not mind readers, so if you don't say anything our tutors can't tell what you are thinking!”
Oxford Computer Science: How to apply“the people interviewing you are interested in how you work out your answers and how you think”
University of Cambridge: Preparing for your interview
