In аll cаses, yоu аre expected tо shоw all of your work and use methods covered in our course. 1.) Show how to reduce each of the following residues. a.) (5127^{2198}pmod{31}) b.) (187^{415}pmod{120}) 2.) Suppose that (gcdleft(a,95right)=1). a.) According to Euler's Theorem, what positive power of (a) is going to be (1pmod{95})? b.) Show how to find a smaller positive power of (a) that is also guaranteed to be (1pmod{95}). 3.) Let (N=493920=2^{5}cdot 3^{2}cdot 5cdot 7^{3}). Find each of the following values. a.) (sigmaleft(Nright)) b.) (tauleft(Nright)) c.) (varphileft(Nright)) 4.) Show how to find three different numbers (n) that have (tauleft(nright)=10). 5.) Show how to compute the largest power of (3) that divides (120!). 6.) Suppose that (Fleft(nright)=displaystyle{sum_{dmid n}}fleft(dright)), and that the first (20) values of (F) are as in the following table. Show how to find (fleft(18right)). (begin{array}{|c|c||c|c|}hline\n&Fleft(nright)&&n&Fleft(nright)\hlinehline1&1&&11&21\hline2&4&&12&66\hline3&6&&13&32\hline4&11&&14&48\hline5&5&&15&30\hline6&24&&16&74\hline7&12&&17&40\hline8&23&&18&80\hline9&20&&19&46\hline10&20&&20&55\hlineend{array}) 7.) Use the fact that (1775=5^{2}cdot 71) to show (111^{222}+123^{122}equiv 100pmod{1775}). 8.) Show that (8911=7cdot 19cdot 67) is an absolute pseudoprime. 9.) Use the fact that (914^{2}equiv 817^{2}pmod{55969}) to factor (55969). 10.) Use the table on the following page to factor (237511) via Karitchik's method. Hint: You will only need two lines.
