How do u get the answers to ixl seventh grade~ "understanding negative exponents" because it's really hard!

I don't have this calculator, but let's give this a shot and see if it gives us the correct answer.

Let's try 10 to the exponent -2. The rule for negative exponents is to put 1 on the top and the term with a positive exponent on the bottom. In this case, it would be 1 on the top and 10 to the exponent 2 on the bottom, or 1 / 100 or 0.01.

In the calculator, enter 10, hit the x to the power of y key, left bracket (, the negative key (-), 2, the right bracket ), and finally the = key. You might not have to enter the left and right brackets, but I like to enter them to understand what I enter in brackets is the exponent.

Let me know if it works and if you have any other questions.

Good luck.

Check the understanding of the problem you are dealing with. The result is much too be for any practical application. result is greater than 10^500.

Yes, it is. It's much better to get the answers right.

Apparently you're calculating 1x10^-14 / 3.3x10^12
Note the positive exponent on the denominator. Make sure you use the (-) key to enter a negative exponent.

To do fractions, input like this:
(1/3)+(4/9)
Granted the answer is a decimal... But you should be able to convert that to a fraction using what you've learned in math class.
PI sign: Just press [2nd]and then[^]. And voila, instant π! Exponent:enter more complicated expressions involving exponents using parentheses and the negative sign.

You must put all negative numbers in Parenthesis otherwise your calculator is not squaring the negative .
