# How do you solve #5(1+10^6x) = 12#?

Rearrange and take logs if necessary to find

#### Explanation:

I'm not sure whether your question appears as intended, so I will answer both interpretations:

Divide both sides by

#1+10^6x = 12/5#

Subtract

#10^6x = 7/5#

Divide both sides by

#x = 7/(5*10^6) = 0.0000014#

Divide both sides by

#1+10^(6x) = 12/5#

Subtract

#10^(6x) = 7/5#

Take common logarithms of both sides to get:

#6x = log(7/5)#

Divide both sides by

#x = log(7/5)/6 ~~ 0.02435#
