TI BA II Plus Cube Root
Timecodes:
in this video I'm going to show you how
to find a cube root on your Texas
Instruments calculator and this is
something that confuses a lot of people
so you should know from basic
mathematics that there's an equivalence
between roots and powers so the cube
root is the same as the power of 1/3
where basically this number goes on the
bottom and then the power of X goes on
the top so this is squared you'd have a
2 at the top but since power 1 you have
a 1 so there's an equivalence between
that so instead of try to find the cube
root button we just put in a power of
1/3 so we'll do a simple example which
is a cube root of 27 which is 3 so to do
this we do 27 and press equals that puts
into the memory then go Y to the X which
is this button then press 3 and then 1
over X so 1 over X is here and then
press equals and it gets 3 and that's
how you find a cube root very simple
just enter 27 and then wipe the X and
then the 1 over X that's all you need
and that works every time
so hopefully this video is helpful to
you and thank you for watching
