ofとtoの違いはなんですか？ 例文もつけて教えて欲しいです！！

F1a-158 ①(2)の解説のピンクの蛍光ペンを引いたところがわかりません。 ②①の質問とかぶるところがあるかもしれないのですが、約数の個数の求め方は公式を覚えてるので解けるのですが、なぜ素因数分解したらそれを元に総和が分かって、左の表のようになるのですか？表がよく分か... 続きを読む

例題 158 約数の個数 男の金 **** (1)(a1+az)(bi+b2+ba+ba) (ci+C2+ca) を展開すると,異なる項は何 個できるか. X2200の約数の個数とその総和を求めよ.また,約数の中で偶数は何 個あるか ただし, 約数はすべて正とする. 考え方 (1) (α)+α2)(b)+b2+bs+ba) (Ci+C2+c3) たとえば, (a1+a2)(by+b2+bs+bs) を展開してできる arb に対して, a*bi (Cr+C2+cs) の展開における項の個数は3個である (a1+az)(bi+b2+bg+b4) を展開するとき, abı のような項がいくつできるか考 えるとよい.

④のbecauseまでの英文解釈をどなたかお願いしますm(_ _)m

travel completely. However, it's never easy to discuss anything that's out of sight to the naked eye, because people are often indifferent to things they can't see. Also, it may be unfair to ask some countries to call off their space plans

The teacher has provided some information. 問1 Yentonville has 3 a church built 250 years ago when the city was constructed Tours of Yentonville The Yentonville Tourist Office offers three city tours. The History Tour BB [] [ The day will begin with a visit to St. Patrick's Church, which was built when the city was established in the mid-1800s. Opposite the church is the early-20th-century Mayor's House. There will be a tour of the house and its beautiful garden. Finally, cross the city by public bus and visit the Peace Park. Opened soon after World War II, it was the site of many demonstrations in the 1960s. The Arts Tour The morning will be spent in the Yentonville Arts District. We will begin in the Art Gallery where there are many paintings from Europe and the US. After lunch, enjoy a concert across the street at the Bruton Concert Hall before walking a short distance to the Artists' Avenue. This part of the district was developed several years ago when new artists' studios and the nearby Sculpture Park were created. Watch artists at work in their studios and afterwards wander around the park, finding sculptures among the trees. The Sports Tour First thing in the morning, you can watch the Yentonville Lions football team training at their open-air facility in the suburbs. In the afternoon, travel by subway to the Yentonville Hockey Arena, completed last fall. Spend some time in its exhibition hall to learn about the arena's unique design.
