That's the answer I get for

30 times log of 1/2 times 83 divided by 8000

or

30 x log(1/2) x 83 / 8000

Are you sure you have the problem specified correctly?

Use the change sign key marked (-) or +/-. Press the (-) key then the number.

The "log" button directly beneath the "2nd" button should work. It just says LOG, but it is to the standard base 10.

You're not calculating the square of a negative number, you're calculating the negative of a square. You need to use parenthesis to indicate the square of a negative number.

You're calculating -(3^2), not (-3)^2.

To calculate the latter: ( (-) 3 ) x^2 =

I'm assuming the lack of a response means using the proper key did the trick.
