If the polynomial 6^4−9^3−2^2+− is exactly divisible by the polynomial 32−4, then find the values of a and b.

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:

hope this !
