Converting numbering systems other than base 10 into base 10 can be helpful due to your extensive experience with base 10. Given a number x of length n in base b+1,xb+1:xn1xn2x2x1x0, write a formula to convert it to base 10. Example for base 2:(xn12n1)+(xn22n2)++(x121)+(x020) 2 (2 points) What are the most negative and positive integers in 12-bit two's complement notation?
