There isn't a problem per se. The calculator is simply showing you the result as an improper fraction.
Press the S--D key to toggle the result between symbolic and decimal forms. To have the results always come up in decimal, press SHIFT [SETUP] 2 to select the LineIO mode.

SOURCE: HOW CAN I INSERT THE
Same question, same answer.
Sorry, but you cannot.
You can type in a formula that involves the memory variables X,Y, A, B,C,D, E, =, . Such a formula is meant to be evaluated to get a solution (X by default). Once you type the formula you press the Shifted function SOLVE and you will be prompted for the constants, for Y etc. when you press the EXE/= key you get the value of X.
If you turn off the calculator or change the calculation MODE, it is wiped out of memory.
To make a long story short, you cannot STORE formulas in the calculator. Better try to memorize them (commit then to YOUR OWN memory).

If you have the so-called xRoot key you procede as follows; 10[xRoot] 1.797
If you do not have an xRoot key you use the equivalence nth root of x= x to the power of 1/n
In the case of the 10th root you type (1.797)^(1/10) or (1.797)^(0.1). Here the [^] caret is the general power key. On some calculators it is marked as [X^y] or [Y^x]
