What is the remainder of (32^31^301) when it is divided by 9?
a. 3
b. 5
c. 2
d. 1

• 32%9=5
  =>(32^31^301)->(5^31^301)

• Z=301 %4 =1; (1st divide by 4 and get rem.)
  Y=31 %10=1; (2nd divide by 10 and get rem.)
  
  b=Y^z= 1^1=1;
  a = b%10= 1% 10 =1; ( again divide by 10 and get rem. )
  
  lastly, 32^ a= 32^1/9 and get rem. = 5
