Distributive property of multiplication?
OpenStudy (anonymous):
uh?
OpenStudy (anonymous):
(m-5) * 10 correct?
OpenStudy (anonymous):
that is the same as (m*10) - (5 * 10)
OpenStudy (anonymous):
ok

you have to add
OpenStudy (anonymous):
Sum/difference of two numbers time a third is the same as the first # times the third add/subtract the second times the third
OpenStudy (anonymous):
the problem is (m ^negative5)10
OpenStudy (anonymous):
oh
OpenStudy (anonymous):
\[(m ^{-5})^{10}\]

like that?
OpenStudy (anonymous):
or is it like \[(m ^{-5})10\]
OpenStudy (anonymous):
like the first one
OpenStudy (anonymous):
oh ok
well there are a whole set of rules with exponents
OpenStudy (anonymous):
but for this equation, there are rules about exponents being multiplied when it's like that

yes I know about the product rule, etc but see we haven't had an example like this one thou
OpenStudy (anonymous):
it's like \[m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5} \times m ^{-5}\]
OpenStudy (anonymous):
ohhh pretty much 10 times
OpenStudy (anonymous):
yeah you multiply the exponents
OpenStudy (anonymous):
but what it means when it saids no exponents tho

so I will multiply 58585....10 times
OpenStudy (anonymous):
opsss 5*5*5*, I meant
OpenStudy (anonymous):
well you can't really get an answer without exponents
OpenStudy (anonymous):
unless you know m
OpenStudy (anonymous):
so you can't simplify this problem

unless it literally means.. you will just write.. m fifty times
OpenStudy (anonymous):
lol I understand
OpenStudy (anonymous):
thank you sooooo much, this problems are very tricky
OpenStudy (anonymous):
\[\frac{ 1 }{ m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m \times m}\]
OpenStudy (anonymous):
like that..

which is dumb in my opinion.. because you represent the same thing with exponents
OpenStudy (anonymous):
correct
OpenStudy (anonymous):
can you help me in this one, I did it already but I don't know if I did it correct
OpenStudy (anonymous):
k
OpenStudy (anonymous):
a+7 over7 ;a

OpenStudy (anonymous):
I did this: 9 over 7 + 7 over 7 = 16 over 7
OpenStudy (anonymous):
is it right???
OpenStudy (anonymous):
\[\frac{ (a + 7) }{ 7 } \times a\]
OpenStudy (anonymous):
is that the equation
OpenStudy (anonymous):
well it don't have the x sign, it has ;

OpenStudy (anonymous):
does it mean the same?
OpenStudy (anonymous):

OpenStudy (anonymous):
ok, I added
OpenStudy (anonymous):
Oh how much I hate math :<(
OpenStudy (anonymous):
is it an equal sign

IDK it only shows the semicolon sign ;
OpenStudy (anonymous):
what are you trying to find
OpenStudy (anonymous):
this problem A+7 over 7 then ;A on the side, the way you wrote it on the side but without the X, only ;
OpenStudy (anonymous):
hmm..
OpenStudy (anonymous):
interesting.... since i'm not sure by what the semicolon means i don't really know what to do
