Question #26099
find the base of the numeral system in which 26-18=9(express your answer in base 10).
Expert's answer
The number 26 in its respective base b is equal to 2*b+6.
If the number 26 were in base 10, then it would be equal to 2*10+6.
The number 19 in its respective base b is equal to 1*b+9.
If the number 19 were in base 10, then it would be equal to 1*10+9.
Compose the equation 2b+6-(b+8)=9, b-2=9, b=11. Therefore the base of system is 11.
