Hi!

Is there also a short form for "3 elevado a 2 igual a 9"? Would "3 a 2 son 9" work? (and is that even the correct translation of "to the whatever power"?)

Also, can I drop the "por" when variables are involved? Like "2 por x" -> "2 x"? 

I get this message even after I click around for awhile:

You took this Kwiz 16 minutes ago.

This lesson is already in your notebook. Go to your notebook now to kwiz this topic as many times as you like.

'Estos últimos días ____ un calor terrible.' Would make me think they are in the past. today does not fit in them. or DOES it, becaus of 'Estos' ? because it talks about the last days (similar to 'last week' or 'yesterday') I presumed I had to use el indefinido (hizo), instead of the perfect (ha hecho).

Apparently I was wrong. So, please clarify, as the exact example is not identifiable in the lesson (to me at least), how I would be able to determine to use the indefinido. IS it because of 'Estos' ?

Thanks in advance!

We were told to form an adverb you take the feminine form and add 'mente' so it would effectively be 'Amente' So why does it say fuertamente is wrong, it's fuertEmente? 

why does uno change "a la una", but ocho does not "a las ocho en punto"? Thank you!

Entender means understand, but in this example: Ella entiende de arte. - means: She knows about art. Why?

Thank you so much!

Unfortunately, I cannot distinguish some sounds, as I have no ear habit. What can I do? 

Thanks for you help.
