@thadyoung XDDD
But if you multiply those numbers then it doesn't equal any of those answers
I assume you mean 4^2 * 4^8 that is 4 times itself 10 times
The answer to the multiplication isn't one of the options, so it must be something else.
@phi yes
do you now that \[ 4^2 = 4\cdot 4 \] ? and \[ 4^8 = 4 \cdot 4\cdot 4\cdot 4\cdot 4\cdot 4\cdot 4\cdot 4\] do you see that putting a little 8 in the upper right is short-hand for multiplying 4 times itself 8 times?
so the answer is \[ 4^2 \cdot 4^8 \\ = 4 \cdot 4\cdot 4\cdot 4\cdot 4\cdot 4\cdot 4\cdot 4 \cdot 4 \cdot 4\]
so c
I posted the answer. count the number of 4's how many are there being multiplied together?
