Exponentiation by Squaring

This is my third video after reading about exponentiation by squaring and being lost, and I understood within 2 minutes. This was super helpful, thanks for making this!

Wow, I've never learned so much so fast, this is even better than Khan Academy!

Great visualization with the program!!!

What I would do is this:
Write k (the exponent in question) in binary and read across.
"New step" after your first x means "square the result."
Only if there's a 1 anywhere from here out, that means "whether or not you'll need to square the result again, multiply by x first."
If there's a 0, that means "for this step, there's no need to multiply in an extra factor of x."

gotta say, ur explanation is great

Thanks bro, thanks a lot!!!!!!!!!! everything about this explanation is perfect!

does the compiler or interpreter automatically take advantage of bitshifting with splitting by binary position to calculate powers of 2?

woooow amazing explanation, i really appreciated it .

This video is really awesome!

Wooow.. your video is really cool...

Wow video..where are you bro..why do you not continue to teach on RUclips..you could be a great tutor here..
