Question

9^10n-12=1/6561

Answer 1

solving for n yes?

Answer 2

is it 9 ^ (10n) or (9^10)*n - 12 = 1/6561

Answer 3

yes solving for n. and it's 9 ^(10n-12)= 1/6561

Answer 4

ohh okies.

Answer 5

(10n - 12)log 9= log ( 1/ (3^8))

10n - 12 = { log ( 1/ 6561) } / {log 9}

10n = { log ( 1/ 6561) } / {log 9} + 12

n= [ { log ( 1/ 6561) } / {log 9} + 12 ] / 10

Answer 6

n = ( -4 + 12) /10

Answer 7

I think this is right, but somebody should check. Haven't done exponentials in a while

Answer 8

the answer choice is a: n=8/5 b:n=4/5 c:n=8 D:n=9/10

Answer 9

neither have I

Answer 10

Oh i put in calculator. It's right. 4/5 is the answer =D

Answer 11

steps are up there if you need

Answer 12

alright thanks!

Answer 13

no problem
