STO 05, FIX 4, etc. are not allowed because to enter them you must press a digit key which then shows the digit in the display.

1/x, 10^x, x^2, etc. if you wish ARE allowed because you did not need to press the digit keys to enter a digit in the display.

STO 05 by pressing STO LN is also not allowed. Use the stack.

Sorry... really not trying to make this tough, just wanting old fashioned efficient stack usage and to challenge getting a couple of specific numbers without using digit keys to help out.

Remember, we all want to learn and have fun :-)
