Well for this question you can factor like this: 7^3(7^3 + 7^2 -7) = 7^3(385) = 7^3(35)(11) = 7^3(7)(5)(11) = 7^4(5)(11) :))) I hope this is helpful have a nice day
Hmm, interesting one way would be to multply it out or set it equal to 11x where x is a whole number (if x is not a whole number, then it is not divisible) 11x=7^6+7^5-7^4 undistribute 7^4 11x=(7^4)(7^2+7^1-1) 11x=(7^4)(49+7-1) 11x=(7^4)(55)
