Question

17. If t^98 +98 is divided by y + 1. the remainder is: a.96 b.97 c.98 d.99​

Answer 1

Answer:

Rule :- Expression will give the same remainder as the expression where Ar, Br, Cr, Dr, Er are the remainders when divided by K individually.

2^86 / 9 can be simplified as

2*2*2 = 8. Remainder of 8/9 is 1. We can form 28 such groups of (2*2*2) and every group will give us the remainder as 1. After forming 28 groups we are left with 2*2 which when divided by 9 will give the remainder as 4

Now apply the rule cited above

Remainder of 2^86/9 is the same as remainder of ----------> ---------> 4
