10^8n−8=1÷10,000

OpenStudy (cwrw238):

10^8n = 8.0001 8n = log 8.0001 n = log 8.0001 / 8 = 0.11288 correct to 5 dec. places

I'm not sure that's right. This is the problem: \[10^{8n-8} = 1\div10,000\]

OpenStudy (cwrw238):

its not right- the way you wrote it is ambiguous

OpenStudy (cwrw238):

ok so 8n - 8 = log 0.0001

OpenStudy (cwrw238):

log 0.0001 = -4 can you continue?

OpenStudy (anonymous):

Yeah. Thanks!
