1\times \frac{1}{100000}=39d
Calculate 10 to the power of -5 and get \frac{1}{100000}.
\frac{1}{100000}=39d
Multiply 1 and \frac{1}{100000} to get \frac{1}{100000}.
39d=\frac{1}{100000}
Swap sides so that all variable terms are on the left hand side.
d=\frac{\frac{1}{100000}}{39}
Divide both sides by 39.
d=\frac{1}{100000\times 39}
Express \frac{\frac{1}{100000}}{39} as a single fraction.
d=\frac{1}{3900000}
Multiply 100000 and 39 to get 3900000.
