Q:101^102^103 mod 201 R?

@Brooklyn said:
ye kya funda lagya hai tune??
are dekh square are either 3k , 3k+1 form..
so equation me daala..toh dono 3k nhi ho skte . n na nhi 1 3k and 1 3k+1...dono 3k+1 wala form hne chahye..so a and b 3 k multiple nhi hnge..becuase unka square 3k form ka hta he
further narrowing down, all squares leaves remainder of 0, 1,4 with 8
1947 leaves rem 3
so LHS ka 1hi combination hga ya 1 + 2(1) = 3
matlab a and b me wahi squares aayenge jo 1 rem dete he 8 k sath..uske baad count count krke...much more compact solution needed!!!

67 prime,

so 102^103 mod 66 = 60

now

101^60 mod 67

u get 34^60 mod 67

17^30 mod 67 so on

17^30 tak karke chod diya ...lengthy hain saala

In a square PQRS, T is the midpoint of PQ and U is any variable point on QR. What is the minimum possible value of 'SU + UT' (in cm) if the side of the square is 2 cm?
(a) 2_/2 (b) _/5 +_/2 (c) 1+2_/2 (d) _/13

T-(1,0)
S-(0,2)
U-(2,y)

root(4+(y-2)^2)+root(1+y^2)

d) _/13
