Question
11. (a) [Sharescreen]/[Verbal] Write the following statement using mod notation: the
last digit of n³ is the same as the last digit of n.
(b) [Sharescreen] / [Verbal] Hypothesize a mathematical theorem based on the answer
from this problem and the previous two.
Hint: As long as n is less than the respective mod,
21
n²¹ (mod 33) = n
n25 (mod 35) = n
n25 (mod 39) = n
n33 (mod 51) = n
n³1 (mod 62) = n
n61 (mod 77) = n
n65 (mod 85) = n
n73 (mod 91) = n
n61
(mod 93) = n
n? (mod ?) = n
