A) equations involving imaginary numbers like these are practically inapplicable
B) equations involving such imaginary numbers have no practical applications - CORRECT
C) equations involving these inapplicable imaginary numbers are practical - misplaced modifier
D) equations involving imaginary numbers such as these are inapplicable practically - awkward
E) there is no practical applications for equations involving such imaginary numbers as these - lengthy and awkward


B is the best option.

It contains 'such' not like and it is short and concise and is in active voice also.

B is the winner here.

We need the adjective "practical" to qualify applications.

My answer is B.

Can "such as these" be correct in a sentence?

So, you thought I put this question in the wrong forum? ;)


these, this those must be followed by noun so A and D are out. C is just reversed the intended meaning. E is just wordy. so B wins

I went with "B". Could anyone explain if option "E" is grammatically incorrect?

Thanks

E) There is no practical applications for equations involving such imaginary numbers as these ----- there is no practical applications– SV error: it should be - there are no practical applications, since the real subject applications is plural

The word "these" must be followed by a noun, am I right? In that case the only valid answer would be B.

Although the square root of a negative number has no real value, it is not necessarily true that equations involving imaginary numbers like these are practically inapplicable

A) equations involving imaginary numbers like these are practically inapplicable

B) equations involving such imaginary numbers have no practical applications

-I eliminated options C, D and E for the following reasons. After eliminating them, I was left with A and B. B is more precise, and clear in meaning than B is.

C) equations involving these inapplicable imaginary numbers are practical

-This option changes the meaning by making the numbers inapplicable, Eliminated

D) equations involving imaginary numbers such as these are inapplicable practically

-Practically inapplicable is much better than inapplicable practically

E) there is no practical applications for equations involving such imaginary numbers as these

- Wordy. "As these" is an unnecessary add-on

I could come down to a and b but chose a.Isn't these referring to the noun 'Square root...' and is therefore correct?Or like should only be followed by a Noun,never a pronoun?

A) equations involving imaginary numbers like these are practically inapplicable
to state example 'such as' should be used not like

B) equations involving such imaginary numbers have no practical applications
correct

C) equations involving these inapplicable imaginary numbers are practical
changes the meaning. here the point is about equations' , which use imaginary numbers, practical application

D) equations involving imaginary numbers such as these are inapplicable practically
these should be followed by imaginary numbers (noun)

E) there is no practical applications for equations involving such imaginary numbers as these
'is' wrong 'are' should have been used. Wrong usage of these. Changes the original meaning

A) equations involving imaginary numbers like these are practically inapplicable --> these can't refer to the singular noun 'the square root of a negative number'
B) equations involving such imaginary numbers have no practical applications --> correct
C) equations involving these inapplicable imaginary numbers are practical
D) equations involving imaginary numbers such as these are inapplicable practically
E) there is no practical applications for equations involving such imaginary numbers as these
