```Using Scientific Notation with Calculators
To change a value to scientific notation:
With Ti-36X Solar
With Ti-30Xa
•Enter value
•Hit
key
•Press
(by hitting 6)
•Round to the correct # sf
•Enter value
•Hit
key
•Press
(by hitting 5)
•Round to the correct # sf
Using your calculator, convert the following to scientific notation:
a) 38666
3.8666 x 104
b) 0.00407
4.07 x 10-3
c) 1300 (to 2 sf)
1.3 x 103
d) 1300 (to 3 sf)
1.30 x 103
To change a value to standard notation:
With Ti-36X
36X Solar
•Enter
Enter value ins sci. not. by entering
coefficient then
EE followed by (+/-)) if negative exponent,
then the value of the exponent
•Hit
key
•Press
(by hitting 5)
Add trailing 0’s to get the correct# sf.
With Ti-30XA
•Enter
Enter value ins sci. not. by entering
coefficient then
EE followed by (+/-)) if negative exponent,
then the value of the exponent
•Hit
key
•Press
(by hitting 4)
Add trailing 0’s to get the correct# sf.
Using your calculator, convert the following to standard notation:
a) 4.85 x 10-3
0.00485
b) 3.270 x 103
3270. (decimal is import)
c) 3.270 x 102
327.0 (zero is import)
d) 8.819 x 10-6
0.000008819
e) 4.5500 x 103
4550.0
Using Scientific Notation with Calculators
Calculators do not give us significant figures. We must figure that part
out for ourselves!
Express the following in scientific notation.
a) 21357
2.1357 x 104
b) 0.00374
3.74 x 10-3
c) 238500000 (to 4 sf) 2.385 x 108
d) 238500000 (to 7 sf) 2.385000 x 108
e) 0.00089300 (to 4 sf) 8.930 x 10-4
f) 0.00089300 (to 2 sf) 8.9 x 10-4
