Maybe your syntax is incorrect. But more likely, it gives the right answer but you do not recognize.
Look on the narrow indicator band on top of the screen. If there is a Math indicator you are in MthIO (textbook display). In this mode results are in the form of radicals
SQRT(76) =2*SQRT(19) Here SQRT represents the radical (square root symbol).
If there is no Math indicator, your calculator is in LineIO and all results are in decimal form so that SQRT(76) =8.717797887
To set MthIO press [SHIFT][MODE][1:MthIO]
To set LineIO press [SHIFT][MODE][2:LineIO]
To toggle between radicals/fractions to decimal press [S<=>D] key above the [DEL] key.

If the result is already calculated and displayed, press the
[S<=>D] key It will convert a fraction or radical to decimal. This
is always possible. If the result is decimal it may be converted to a
fraction or a radical (Not always possible).
If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].
More permanently. If you do not care for fractions and radicals, set the Input/Outpout mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]
