write it in terms of 3^___
OpenStudy (volleyballlover55):
oh ok.. 1 / 3^16
Vocaloid (vocaloid):
good
[ 2^(-5) ] ^ (-2) = ?
Vocaloid (vocaloid):
(in terms of 2 ^ _____)
OpenStudy (volleyballlover55):

Vocaloid (vocaloid):
not quite
Vocaloid (vocaloid):
answer should be in the form 2^____
Vocaloid (vocaloid):
just multiply the exponents together and fill in the blank
OpenStudy (volleyballlover55):
i dont know this one...
Vocaloid (vocaloid):
what are the exponents?

OpenStudy (volleyballlover55):
-5 and -2
Vocaloid (vocaloid):
now multiply them together
OpenStudy (volleyballlover55):
10
Vocaloid (vocaloid):
good so 2^10
Vocaloid (vocaloid):
now do
(9^0)^(-2)

and while we are solving this problem.. make sure to tell me the steps as well..
what are the steps so far?
OpenStudy (volleyballlover55):
9^-2
Vocaloid (vocaloid):
i'm showing you the steps.......
Vocaloid (vocaloid):
and no
Vocaloid (vocaloid):
again, multiply the exponents together

i know but in words..
OpenStudy (volleyballlover55):
like #1. blah blah blah...
and then show the actual work
2.etc..
Vocaloid (vocaloid):
just explain what i'm doing in words
OpenStudy (volleyballlover55):
yes ofcourse
OpenStudy (volleyballlover55):
i dont know what we are doing exactly...

Vocaloid (vocaloid):
simplifying the first part of the expression
Vocaloid (vocaloid):
we have
(3^8 * 2^-2* 9^0)^-2
so we're simplifying this by multiplying the inner exponents by the outer exponents, and keeping the bases
OpenStudy (volleyballlover55):
i only know the first step :
apply the rule of multiplying exponents
OpenStudy (volleyballlover55):
ok and the second step?
Vocaloid (vocaloid):
we're still not done with the first step
what is (9^0)^(-2)?

Vocaloid (vocaloid):
good, let's write down what we have so far
OpenStudy (volleyballlover55):
ok..
