# this is the simplest way- show all but the last 10 digits
print str(28433*pow(2,7830457)+1)[2357197:]

# which is equivalent to 
print (28433 * 2**7830457 + 1) % 10000000000

# which is equivalent to
print (28433 * pow(2, 7830457) + 1) % 10**10

# which is equivalent to
print (28433 * pow(2, 7830457)) % 10**10 +1

# with three arguments, pow is equivalent to (x**y) % z
# but i don't understand this exactly 
print (28433 * pow(2, 7830457, 10**10)) % 10**10 +1
