Finding present value (microeconomics), creating a shortcut on PTC Mathcad

PV: present value
FV: future value

I am earning 300000 per year with a discount rate of 5%.

Formula: PV=FV*(1+r)^-n

What will me present value be after 6 years.

My problem is when im plugging numbers in, it takes a lot of times when plugging all the numbers in.

Is there any way to make some kind of shortcut??

This is how i am doing it right now.
