49^{8}+7^{14}=(7^2)^{8}+7^{14}=7^{2*8}+7^{14}=7^{16}+7^{14}=7^{14}*(1+7^2)=7^{14}*(1+49)=7^{14}*50

Таким образом, значение этого выражения действительно делится на 50

Відповідь:

Покрокове пояснення:  49^8+7^14=7^16+7^14=7^14*(7^2+1)=7^14*50.

В произведении есть множитель 50.  Значит это произведение делится на 50.

Letter of complaint
Write a word which best fits into each gap!

Dear Manager,
I am writing to complain ... our recent holiday, ...we booked through your company at ...beginning of February. My friend and I feel that the advertising of this holiday was misleading, the organization poor and the cost too .... If we ....known what it was really going to be like, we definitely ...not have chosen it.Right from check-in at the airport, ... was supposed to be at 5.45 in the morning, things started to ...wrong. Your staff there, which appeared to be half asleep, said they had ...record of our booking and neither...them seemed interested in finding ...why. They said we must ... been given the wrong tickets and suggest we ...in touch with the main office, which of course was closed at that time in the morning. Our holiday ...have ended there and ...if the supervisor had ...appeared by chance and eventually sorted things out.
 The flight itself, which ... have taken off at 7.45 but was delayed for almost the whole of the morning, was uncomfortable and the food, when at last it was served,couldn't be eaten. ...we landed, we found the buses which we had been promised, had long since aft (to be very old). ... the time we reached the hotel, we were already wishing we had stayed at ... , but even worse was to come.
 The hotel, advertised in the brochure as a luxury location, was appalling. The room was tiny and the food, ...my opinion, disgusting. There was, in fact, so much wrong with the place, so ... we collected evidence in the form of photos, which I enclose.
Needless to say, the return flight was also late and took ...more than six hours behind schedule. I travel very often, and I am not ...to such poor service. My friend and I feel there ...be no excuse for this and we expect you to offer us a considerable ...of money in compensation. If this is not forthcoming, both of ... will take legal action to obtain it.
Yours faithfully,
Jonathan King
