An airplane is flying from New York to Houston at an altitude of 49,000 feet. There are 5.280 feet in one mile. To the nearest mile, what is the altitude of the plane?​

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

a             it is the sum of the initial amount and the additional amount after d days.
