Don't get scared by the appearance of the question!
Factorize the common factor 42010:
4^2013 - 4^2012 - 4^2011 + 4^2010
=(4³-4²-4+1)*42010
=(64-16-4+1)*42010
=45*42010
=45*(2²)2010
=45*24020
By inspection, x=4020.
Hi I need help on how to do this exponent problem thanks.
solve for x:
4^2013 - 4^2012 - 4^2011 + 4^2010 = 45(2^x)
