What I have been doing is just taking a fraction and raising it to ^(1/2) to find the difference of squares and it has worked for every problem except this one, and it seems to be a fault with the calculator.
For some reason in my TI-83 if I just enter it will yield
but if I do , turn it back into the fraction and then raise that to it will give me the correct fraction
Very strange indeed, anyone know why the calculator might be doing this?
Same thing for if I just try to raise this to ^(1/2) in the calculator it will yield 1.333 repeating, which equals when converted back to a fraction. But if I do it will yield .444 repeating, turn it back into the fraction and then I can raise that to ^(1/2) to get the correct answer which is
