I am trying to calculate powers with my Texas Instruments BA ii plus, but big powers such as ^360 gives me an error msg. How can I solve this problem? Thanks!

Break the problem up into smaller pieces.

There's a limit to how big a number the calculator can represent. Numbers as large as 10 times 10 to the 100 simply can't fit into the calculator. For really large numbers, calculate the mantissa and the exponent (power) separately.

For example, to calculate 2^360, first calculate 2^300: press 2 ^ 3 0 0 = and see 2.037036*10^90. Divide by 10^90 (and remember the 90): / 1 0 y^x 9 0 = and see 2.04. Multiply by 2^60: * 2 ^ 6 0 = and see 2.348543*10^18. Multiply that by the 10^90 we took out earlier by adding exponents and write down 2.348543*10^108. That number is too large to fit into the calculator but we got it by calculating the 2.348543 and the 108 separately.

How to turn off calculator

Most calculators have a key sequence to turn off power. The key may be dedicated (one function) or it can be activated by pressing SHIFT or 2nd first. For a Casio scientific calculator, press SHIFT followed by AC (All clear). Some solar powered calculators do not have a key to power off but the calculator will turn itself OFF after a moment of inactivity.

How to work to the 2nd and 3rd powers

Most calculators have a power key. It may be marked "^" or "x-superscript-y" or similar. This key can be used for any power, not just 2 and 3.
Many calculators also have a dedicated 2nd power key, typically marked "x-superscript-2". Some calculators also have a 3rd power key.

How do you calculate a exponent thats a fraction? (24/76) with a power of 1/7?

Enclose the base 24/76 with parentheses, and do the same for the exponent 1/7
(24/76)^(1/7). The caret ^ represents the general power key. On your calculator that key may be marked X to power y or Y to power x.

I want to calculate powers on my calculator but am unsure what buttons to press

You have two buttons to calculate powers: The [x^2] calculates the square of a number while the [caret ^] key allows you to calculate any power, be it with integer, fraction or negative exponent.
Both keys are next to one another, one below OPTN and the other below the VARS key.
To calculate roots, you have the square root [SHIFT][x^2] the xroot key [SHIFT] [caret ^] , the CUBE root [SHIFT] [(] , and the inverse key [SHIFT][).

My HP 10s Scientific calculator does not switch on what could be the problem, is it maby because the calculator was left in a drawer and now the batery ran flat hou can I charge it on the solar power...

You can't charge the calculator off the solar power panel. The solar power panel merely conserves battery power when using the calculator in a bright environment. Try putting in a new battery and see whether the calculator turns on.

How do you calculate for example 0.90 to the 9th power?

Once you know how to raise a number to a power you know how to calculate any power. It is all done the same way: Use the caret ^ key.
0.9^9 =0.387420489
Hope it helps.

Casio calculator fc-100v, to the power of?


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.
