0.00105 in sceintific notation show work

The calculator can show the results in radical form if it involves square roots. The 4th root of 243 is 3 times the fourth root of 3, which unfortunately is beyond the calculator's capabilities to display in radical form. Try taking the fourth root of 3 (or equivalently, the square root of the square root of 3) and you'll see the calculator display the result in decimal.

The error is in the eyes of the beholder. In scientific notation your value of 0.0095 is written as 9.5*10^(-3). Actually the calculator showed you more digits than you were asking for and its answer is more precise that yours. When you choose the Input/Output of the calculator to be LineIO, it will show the results as decimals. Howvever if the number to be displayed is too small or too large, the calculator will use the scientific notation.

To do exact calculations (whenever possible) set the Input/Output mode to MathIO. The result will be a fraction (19/1981). After that you can press the [S-D] button to convert that exact result to its decimal representation.
If you do not mind my advice, I suggest you learn how to interpret scientific notation, and familiarize yourself with the capabilities of this new type of calculators.

To configure the calculator for MathIO, press [SHIFT][MODE] to open the (SetUp), then select [1:MathIO]. In this mode, you will be able to see the expressions you type in as they would appear in a textbook:Fractions will appear as fractions, you will see radicals, etc. You can do a string of calculations in MathIO and convert only the last result to its decimal representation.

Your calculator is set to display results in engineering notation, where the exponent is always a multiple of three. To change the display notation, press the MODE button. Use the arrow keys to make your selection. You probably want to highlight "Normal" on the top line, press ENTER, highlight "Float" on the second line, press ENTER. Press 2ND [QUIT] to exit the mode screen.

You can download the manual from the manufacturer's web site at

Press 2nd [SCI] to switch the calculator to display all results in scientific notation. The results are the same whether you do it in scientific notation or not, it's just how the number is displayed.

Unfortunately, you can't. From the manual:

If [...] the answer cannot display in 10 digits (or the absolute value is less than 0.001), the TI-84Plus expresses the answer in scientifc notation.

3.38x10[superscript 3] or 3.38E3

For converting answer in to scientific notation do the following steps.

1.click shift key after that press mode key next to on button.

2.From the menu that is displayed in the screen press 7 for displaying answer in scientific notation.

Thank you.

Unfortunately, you don't. For numbers whose magnitudes differ too greatly from 1, the calculator automatically switches to scientific (or engineering) notation. You can press MODE and change the display settings, but there is no setting that will force the calculator to show this number without an exponent.

try again by formatting the card into the camera itself. this may solve the problem.
