<p>I'm really desperate and just need to know what keys to hit to solve this simple math problem. I'll write the problem out since I don't know how to type in exponents.</p>
<p>(8 times 10 to the 4th power) x (7.5 times 10 to the negative 6) x (4.4 times 10 to the 15th) / (1.1 times 10 to the 4th) x (2.5 times 10 to the 3rd)4</p>
<p>The last number 4 is to the 4th power and not 4 times. Again I do not know how to type exponents.</p>
<p>I know the answer is .00614 but I need to know how to get that answer. If someone is kind enough to tell me which keys to hit to solve the problem. PS I know how to use the shift key so to make things shorter you can just say the name of the key. I also know how to use the negative. I think I'm making a mistake on the bottom of the fraction. Could be something as simple as a parenthases but I've been trying for an hour now...</p>
<p>om gosh I've been working on that problem for a friggen hour. Now I get the concept and that will be with me forever! Thanks! Also why do you use ^ for exponents rather then the "10 to the x" key? Also I got the correct answer now but shouldn't the calculator make me put another parenthases at the end of the 1st part of the division?</p>
<p>Thanks! Now How do you punch in this one?
4(the square root of the rest of the problem) (6.63 times 10^-34) x (6.02 times 10^23) / (9.1 times 10^31)</p>
<p>The answer is 1.44 x 10^5
I just don't know how to get that answer.... You have no idea how much stress and time you are saving me. Thank you!</p>
