To evaluate the expression we can use the EVAL function, as follows:
µ„î`
If the CAS is set to Exact, you will be asked to approve changing the CAS setting to Approx. Once this is done, you will get the same result as before.
An alternative way to evaluate the expression entered earlier between quotes is by using the option …ï.
We will now enter the expression used above when the calculator is set to the RPN operating mode. We also set the CAS to Exact, the display to Textbook, and the number format to Standard. The keystrokes to enter the expression between quotes are the same used earlier, i.e.,
³5*„Ü1+1/7.5™/
Resulting in the output
Press `once more to keep two copies of the expression available in the stack for evaluation. We first evaluate the expression using the function EVAL, and next using the function NUM: µ.
