Dear Amit
Hi!
Congratulations on your clearing Class XII with very good marks. But my happiness for your success is mixed with doubt and sorrow because I have come to know that that you use unfair means in exams to score good marks. This is really very unfortunate for us after all the medals our father has got for his honesty. You must understand that dishonest and unlawful practices ultimately lead you into trouble. Only good and honest habits stand by you through all your thick and thin and help you bring laurels to yourself, home and society. There are a lot of such examples before you.
Moreover, the dishonest practices don’t provide you concrete knowledge and so it doesn’t last long. The success achieved thus gives you only transitory pleasure which later turns into frustration and disappointment. Apart from this, the fact cannot be denied that to pass higher and competitive exams one needs substantial knowledge. Copying is in fact a slur on the fair name of education.
I hope now you won’t indulge in unfair practices to get good marks rather you will work hard and prove your intelligence in a proper manner.
Looking forwards to your reply.
Yours affectionately
Ayaan
Answer:
first of all..
Step-by-step explanation:
no. ending with digit 9 have even power gives unit position as 9^2
i.e 1 at unit place.
number 17 have power with given condition gives unit place as 7.
so after multiplication it gives 1*7=7.
