@delicate wraith I can walk you through this
Here’s a power rule that you Will want to memorize
$a^{-b} = \frac{1}{a^{b}}$
@tropic meadow
I understand that part however the answer says 3^-1^-n
I dont understand why 3 has an exponent of negative 1?
in the question they rewrote it like this
dosent the exponent one have to be positive?
Ok first things first:
(3^(-1))^(-n) = 3^n is this
But the task you provided has a different result
yes
İts like the second one
you are supposed to flip 1/3 but the answer is (3)^-1^-n
adonhs
but why not write it as $3^n$
polina.love
$\bigg(\frac{1}{3}\bigg)^{-n} = (3^{-1})^{n}$
adonhs
I want to know why the answer for
$(1/3)^-n$
polina.love
use {}
${1}{3}^-n$
$\bigg(\frac{1}{3}\bigg)^{-n}$?
adonhs
$\bigg(\frac{1}{3}\bigg)^{-n} = (3^{-1})^{n}$
polina.love
Why is this true ur asking?
$(3^{-1})^{n}$
polina.love
giiirl whats ur question
why is it written like this
so why its true
I want to know why its written like this $(3^{-1})^{n}$
polina.love
yes
We can pull the -1 in
$\bigg(\frac{1}{3}\bigg)^{-n} = \bigg(\frac{1}{3}\bigg)^{(-1)n} = \bigg(\bigg(\frac{1}{3}\bigg)^{-1}\bigg)^{n} = 3^{n}$
shoot i am stupid
adonhs
mb😭🥲
no its fine lmao Im the dumb one for asking such an easy question Im going to fail 😢
the thing is I understand that the fraction equals 3^n but why write it as 3^-1^n?
or since they are both equal it dosent matter how you rewrite the fraction with the negative exponent
You mean $(3^{-1})^n$?
adonhs
They are not the same
yes why is it written like that instead of 3^n
They are not the same
hm ok
One is actually 3^n and the other you refer is (1/3)^n
you are supposed to flip fractions with negative exponents right?
ok no prob
ok bro so did you try to solce it by yourself?
can I send a video explaining myself
sure haha
ok hang on for 5 minutes
5min video💀
nooo i mean wait for me to record and send it
I see mistakes
ok what are they
(1/3)^(-n) = 3^n
-9 = -3^2 not -3^3
I get your task now, you have to solve for n
I thought this was some math sequence or some
yes I have to solve for n
n = 2 looks correct
ok cool I think I get it now
Yes the steps are correct
And you said you are gonna fail lmao
I hate how long it is
You gon smash that test
I hate long math steps
Better to hate them then to not get them
Im gonna smash it alright 🕶️
that is true
thank you for the help I appreciate it
thank me by passing😎
Of course, if I ever become a top engineer more than half my earnings will go to you 😎
