Multiplicative inverses.
a) What is the definition of a multiplicative inverse in Zn?
b) Use the definition of multiplicative inverse and trial and error to find the
multiplicative inverse of 3 in Z16. Use the multiplicative inverse to solve 3x +
9 = 15 in Z16
c) Use the Pulverizer to find the multiplicative inverse of 37 in Z45 or explain
why you cannot do so. If you find a multiplicative inverse, use it to solve
37x + 23 11 in Z45
d) Use the Pulverizer to find the multiplicative inverse of 39 in Z45 or explain
why you cannot do so. If you find a multiplicative inverse, use it to solve
39x + 10 = 44.
e) Use the Pulverizer to find the multiplicative inverse of 15 in Z26 or explain why
you cannot do so. If you find a multiplicative inverse, use the multiplicative
inverse to solve 15x + 5 = 23 in Z26.
f) Use the Pulverizer to find the multiplicative inverse of 18 in Z32 or explain why
you cannot do so. If you find a multiplicative inverse, use the multiplicative
inverse to solve 18x + 6 = 30 in Z32.
