the 1st equation is wrong undoubtedly wrong....or may b u have printed it wrong....
for 2nd question...
since 19 is a prime no.....so any power of 19 can b divisble only by
19k type numbers....where k can be any positive no.
since here 92 is not a type of 19k...thrfore....(19^92) is not divisible by 92..
such questions are solved by checking divisibility of various nos. given in problem...like i checked divisibilty of 19 and 92 above
hopw u got me....
