The Expression came in two parts, we started by solving the first part and getting a whole number and the second part was used to divide the first part.
The answer is 12005
Given Data
we have the expression
7^6+7^5−7^4 by 11
The dividend = 7^6+7^5−7^4
The divisor = 11
Let us express the dividend as a whole number
7^6+7^5−7^4 = 117649 + 16807 - 2401
7^6+7^5−7^4 = 132055
Hence the expression 7^6+7^5−7^4 by 11
= 132055/11
= 12005 ans
