Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

we need to calculate 3^256 and we know 3^4 =1 mod(10) so we have to multiply such no. a with 4 such that we get closer to 256 so that 3^4a=1 mod (10) so we can observe we need 4a=256 , a=256/4 a=64

sir pls once tell
there is a property that if n^a= b mod(m) then (n^a)^c= b^c mod(m), so here 3^4=1mod(10) , (3^4)^64=1^64mod(10) , (3^4)^64=1mod(10)
got it now sir thanks a lot sir
always welcome 😊
