Hi,
please help, I just got one of these calculators (fc-100v)& can't figure out how to "to the power of" - e.g 3 "to the power of" 3 = 27, can't find it in the user's guide.
On my old scientific calculator the "power of" button is an x with a cube to the top right. Please help my old calculator died & Ihave an exam coming up.
Many thanks,
Lisa
Hello
To calculate a number to an arbitrary power you use the button labeled ^ .
If you want the cube of 2 your enter
[2][^][3] will give you 8. If your exponent is negative use the sign change key (-) and close the negative exponent between parentheses : for exemple the sequence to compute 2 to power of negative 5 is as follows
2[^] [(] 5 [(-)] [)] which means you enter the value of the exponent before the change sign (-). If you use the big MINUS sign you will get a syntax error.
Hope it helps.

I am guessing, but, find the key that has a 3 to the left of the root symbol, looks like a check mark. Push it, then the number you want to take a cube root of, then enter.

Hello,
1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19
Hope it helps

Hi,
Sorry to disappoint you: This calculator is not programmable.
Good luck.

SOURCE: Finding a cube root on calculator
You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).
