Setting out (1 Viewer)

Say in an exponential growth and decay question which required you to find the value of k and use it to find another value eg of T and t = something.

Instead of writing out the value of k in each step. Am I allowed to just mention that I'm using the value I've calculated in calculator memory?

Eg in 2013 q 12 c

I calculated the value of k as = (-ln(19/20))/10

Then wrote in brackets (calculator memory)

Then proceeded to continue to write k

that's what I do

Yes you can do that
