If x = 4 (mod19) and y = 7 (mod19), then find the remainder when (x + 1)^2 (y + 5)^3 is divided by 19.

Many people have already mentioned this to you, but I will just remind you here again -

 

STOP USING THIS AS A CHEATING SITE

 

You have said many times previously that YOU ARE ONLY INTRESTED IN ANSWERS and not actually how to do them. 

Please stop using this as a cheating site, it gets frustrating for everyone else
