Is there an inverse key on the HP35S and if so how do I access it?

HP Recommended
HP 35S scientific calculator

I have an older book that shows the problem, what is the 3.12 root of 1460 or the yth root of x. There is an inverse key step in the solution that I cannot find a key for on the 35s. If there is an inverse key how do I access it?

The HP-35s also has a key to directly calculate "x root of y". It is orange-shift on the square root key.

Thank you for the 2 replies BartB. At the expense of seeming dense, I am not really familiar with the key sequence to this problem and the manual is not overly enl;ightening. No matter how I try to key in the problem, I keep getting a syntax error. What is the correct way to key this in?

Hi,
Are you using the calculator in Alg or RPN mode?

Sorry for the delay in answering Bart. I have tried both ways. It is a problem of keying in the steps properly. On the 35s I am obviously doing something wrong. Could you please tell me the exact sequence to key in the problem.  the 3.12 root of 1460. According to the book the answer is 10. and a string of numbers. I am more interested in how to arrive at that answer than what the anser is. Thanks in advance.

Hi,

 

In RPN mode:

Method using inverse: 1460  ENTER  3.12   1/x    Y^x

 

Method using xROOTy: 1460  ENTER  3.12 (orange-shift) xRooty

 

 

In ALG mode:

Method using inverse: 1460   Y^x    1/x   3.12   ENTER

display should show 1460^INV(3.12) before pressing ENTER

 

Method using xROOTy: (orange-shift) xRooty 3.12  right-arrow 1460 ENTER

display should show XROOT(3.12,1460) before pressing ENTER
