How to use scientific calculator?
Formula :- y = axb ( a*x to the power b)
a = 1.5
b = -0.0740005
x = 100
HOW TO CALCULATE ????i need your calculator type so i can google it and check what buttons u have.
Mark/model
1.5×100^(-0.074005)=1.066817814 (my CASIO fx-83ES has a bottom for the function x^ but when pressing it, it shows as above so maybe yours has a similar function or bottom).
Best wishes,
Alua

the same problem
citizen sr-135tII100 {xy}.0740005=1.406050762{shift}{x^2}=0.711211876*1.5=1.066817814
Terpsichora, u dont even have to use SHIFT.
a*x then press x^y button (its the first to right of EXP) then u type the long b number 0.785734734…. then press (+/-) button and in the end (:)
Dont enter -0.785734734 just put it as a positive number and just then press (+/-) to tell the calculator its a negative number.

I hope only abc+learning curves will be examined in dec’12)))
thanks again!
may the force be with us!)I’m not sitting the exam until June but do we need a scientific calculator? The bits I have covered so far haven’t required it – but may be I need it later in the book??
