Help!Strange problem with scientific calculator.
I was doing chemical equilibrium problems where one of the steps required me to square the reciprocal.
Which was (1/4.2x10^52)^2
The correct answer for this is 5.7 x 10^-106 but my Casio FX 115 ES calculator keeps showing zero.
Can anyone please shed some insight on this. It would be greatly appreciated. I have used this calculator in the past with success. I never encountered such a problem before. I have my exam on Tuesday. BTW no graphing calculators are allowed. If this doesnot workout then I will have to purchase another scientific calculator.
