Why does 2³ × 2² = 2⁵?
Exponents count factors. The first power has three factors of 2, and the second has two more. Together, that makes five.
When multiplying powers with the same base, keep the base and add the exponents.

0.75 stops. 0.333… repeats.
Both are rational because both equal fractions:
0.75 = 3/4
0.333… = 1/3
A rational decimal either terminates or eventually repeats a fixed pattern. That’s the rule.

math8 Ss @FJHChargers focused on application problems of Pythagorean Thm. Ss started with a 🧩 . Then I introduced them to 📺 show Homestead Rescue. We found the connection & brainstorm other jobs that would use Pyth Thm. Found out 1 of my Ss used to homestead! #seeigmath

Old guy here (76 old). My dad dragged I/O cables between walls programming I think nr 2 mainframe after ww2. Years later built this.
He always said "we couldn't have stopped anything, but perhaps we should have tried to delay it"

My dad designed and produced this. Along the way, HP bought up some patents. They sent him (late 19's !!!) a prototype touch screen desktop. Terrible idea, if you ask me
