in a particular number system multiplication of 41 and 53 is 3133
what is the number when 14 and 35 will be multiplied ?

these numbers are in base 7.
(4x+1)*(5x+3)= 3x^3+x^2+3x+3
3x^3-19x^2-14x=0
3x^2-19x-14=0
x=7

then 14in base 7= 11 in base 10
35 in base 7= 26 in base c10
11*26= 286 in base 10 = 556 in base 7
