My "pick":
A logarithm is what is known in algebra as exponent
are you sure you didn't leave out "in" in option C ? |

That's what confuses me, Alex. My friend sent this question to me and I think it's quite odd. I also suspect there must be something missing or misquoted here. Anyway, I'm just an intermediate learner so I'm not sure what I think is correct.

Hi Nessie
I agree with Alex. ;)
None of the options work, and the only other thing that I would add is that two words seem to be missing from the sentence:
A logarithm is what is known in algebra as an exponent. . _________________ "Nearly all men can stand adversity, but if you want to test a man's character, give him power." ~ Abraham Lincoln |

Hi Amy, can we say this:
A logarithm is what know in algebra as an exponent (without the second "is") I think it is the reduced form of this: A logarithm is what that/which is known in algebra as an exponent.
Thanks a lot. Nessie :) _________________ :(... something we never have again, I know... I guess I really really know.. :(

Why, Amy?
I think these are the same:
- The story which/that was told by her wasn't true. - The story told by her wasn't true. (reduced form) _________________ :(... something we never have again, I know... I guess I really really know.. :(

Hi Nessie
First let me ask you to tell me what these mean, and whether you think they can ever be used: - "it is what know" - "what is know" :? _________________ "Nearly all men can stand adversity, but if you want to test a man's character, give him power." ~ Abraham Lincoln |

Oh God! How silly I was not to realise that typo (+_+) I'm terribly sorry, Amy, I certainly meant "what known as":
A logarithm is what known in algebra as an exponent (I think it is the reduced form of "A logarithm is what that/which is known in algebra as an exponent")
Many thanks and terribly sorry once again. Nessie. _________________ :(... something we never have again, I know... I guess I really really know.. :(

Hi Nessie
No, that still doesn't work. Your examples do not reflect the same sentence structure, and they do not use the word 'what'.
| Quote: |
| A logarithm is what that/which is known in algebra as an exponent. |
It is not possible to combine 'what' with 'that' or 'which' as you have done.
You could theoretically say this: - A logarithm is something that/which is known in algebra as an exponent.
And then reduce that to this (awkward): - A logarithm is something known in algebra as an exponent.
Rather than to reduce as above, it would be better to simply shorten the sentence by omitting the (unnecessary) part in boldface type below: - A logarithm is something that/which is known in algebra as an exponent. (i.e. A logarithm is known in algebra as an exponent.) . _________________ "Nearly all men can stand adversity, but if you want to test a man's character, give him power." ~ Abraham Lincoln |

Once and for all: confronting school kids with the three terms 'power' 'exponent' and 'logarithm' without pointing out that they all essentially mean the same thing amounts to child abuse!
So is the duplicity of the usage of 'power': Consider 2^3 = 8 ( ^ - 'to the power of'): You are told that "eight is the two to the power of three" i.e. 'three' being the power. Than you are told that "eight is a power of two" i.e. the 'eight' being the 'power'
This kind of disregard is one of the causes of Maths being wrongly conceived as 'more difficult' than other subjects.
The book "Demathtifying - Demystifying Mathematics" shows systematically how these unnecessary obstacles can be easily circumvented. |
