I will not do it for you
You get a rung, not an answer. Rung one tells you what the question is really asking; rung three gives the whole method but stops before the value. The last step is yours — that is the part that makes it stick, and it is also why nothing here can be handed in as your work.
The photo is looked at, never stored. I will not state the final answer — that part stays yours.
Exam coming up? The move is not to re-watch the lecture. Paste its transcript once, then ask it the parts you are unsure about — each hint points back at the minute it came from, so review is a few jumps rather than another hour.
If you are being examined right now, this will refuse. Come back after and we will go through it properly.
