A city with a population of 426,000 is forced to evacuate due to a natural disaster. The damage from the disaster caused many residents to move away, and the population decreased exponentially by 26% a year after the disaster.

If the population continues to decrease at this rate for t years, write the expression that reveals the monthly rate of decrease for the population in the form (b)c. Round any decimals to the nearest thousandth.
