Ti-84 convert to scientific notation

I was doing a statistics probability difficulty and I required to find the value of (0.17)^4. When I entered the value right into my calculator, I noticed that it provided me the answer in scientific notation (8.3521E-4). I figured let me attempt entering 8.3521 * 10^-4 hoping that it"d offer me the decimal form I was searching for. However before, it was the same exact issue.

*

I saw the "mode" option of the calculator thinking that there was something wrong via the setting however everything was fine. I don"t mind manually converting the scientific notation into decimal create but I"d really choose for the value to be already in decimal create given the workfill of these difficulties.

Thank you for reading!

Note: I have a TI-84 Plus Silver Edition.

The calculator immediately uses scientific notation for numbers smaller than $0.001$ in absolute worth, no issue what your mode settings are; this cannot be overridden.

The the majority of straightforward means to get the calculator to instantly tell you how many type of zeroes tbelow are after the decimal, in such a instance, is to include $1$:

0.17^4 8.3521e-4Ans+1 1.00083521Just disregard the $1$ in front of the decimal point and also you have actually the answer you want.

Note that in general, this will certainly shed you precision:

0.17^8 6.975757441e-7Ans+1 1.000000698In this case, it"s not as well bad: we deserve to use the second output to count zeroes and the first for even more digits. Sometimes, it will certainly shed you all of the precision:

0.17^16 4.86611919e-13Ans+1 1But in this last instance, maybe you don"t want the number as a decimal after all.

Scientific notation have the right to represent specific numbers if they are terminating decimals. In your case $0.17^4=0.00083521=8.3521E-04$ exactly. Did you drop the final $1$? I would mean the calculator to show it. The calculator most likely does this calculation as $e^4 log 0.17$ and also $log 0.17$ cannot be represented precisely, so there is a reasonable chance that the result is not precise. I wouldn"t suppose that to adjust anypoint as far forward as the fifth area, yet seeing $8.35209999E-04$ would not surpclimb me
