Question

solve the equation 3^n-12=1/81

Answer 1

go nikita!

Answer 2

3^n = 12 + 1/81 = (12*81 +1)/81.
\[\log_{3}3^{n} = \log_{3}((12*81 +1)/81)\]
\[n = \log_{3}(81*12 + 1) - 4 \]
but \[\log_{3}(81*12 + 1) \] not integer. (

Answer 3

my options are 9, 8, -8 and 16

Answer 4

did you want n-12 to be the exponent?

Answer 5

yes

Answer 6

ok put parathesis around you exponents so we know k?

Answer 7

okay sorry

Answer 8

so n-12 = -4

Answer 9

its cool

Answer 10

gj nakita
if you solve n-12=-4 for n you will get your answer

Answer 11

n=-4+12=8

Answer 12

really?)

Answer 13
