|dw:1441903391506:dw|do you know this?
yes what do i do
7 minus 3?
k hold on lemme see
its not 7 minus 3
the 3 is an exponent
so what do i do
|dw:1441904338660:dw|see the pattern?
so we want to go the other direction for negative exponents. to do this we have to do the inverse operation of multiplication. do you know what the inverse operation of multiplication is?
well, technically, we multiply by the reciprocal... but ususally people just call it division.
so if we are at \(7^3\) and we want to get to \(7^2\), we divide by 7 or multiply by 1/7... okay?
do you follow that?
so let's take it a step further... let's figure out what \(7^0\) should be , using the pattern...
can you figure out what \(7^0\) is?
no... let's follow the pattern. what is the number above \(7^0\)?
so what is the number above \(7^0\)
very good!!! now we use the pattern. to go down (negative direction) we divide by 7. what is 7 divided by 7?
it's the same as 7 times (1/7)...
7 divided by 7 is -1 ??? i don't think so, try again
just 1 sorry
|dw:1441905368853:dw|so can you figure out the next number? again, follow the pattern...
7 by one
? if you can use an expression or the the number
so what is it... i don't understand what number "7 by one" represents.
don't be afraid... take your time and think, use the pattern and then respond. it's okay to make a mistake because i will help you to learn from it
sorry my computer went out
that's alright... what did you get?
i thihnk it is c
just so you know... my goal here is to help you understand these types of problems. it is not to just help you get the answer for this problem.
