Answer:

remiander = 21

Step-by-step explanation:

x^21+21 gets divided by x+1 as

x+1/x^21+21

x+1*x^20 = x^21 + x^20 +21, now remainder is x^20+21

then we multiply x+1*x^19= x^20+x^19+21 , now remainder is x^19 +21

then we go on and on till we get as remainder x^2+21

then the quotient will be x and then the the answer will be x^2+x+21 and then x divides x^2 and when 1*x , the remainder is 21
