54 to the power 124 divided by 17
Read Solution (Total 6)
-
- 3^124 = (3^7)^17 · 3^5
Since 7 and 17 are co-primes.
(3^7)^17 will leave the same remainder when divided by 17 as 3^7
=>3^7 · 3^5 = 3^12
And since 3^12 has remainder 4 when divided by 17,
so when 3^124 is divided by 17 gives 4 as remainder.
