Because b cannot be cancelled unless specified that b is not equal to zero

Otherwise taking it to the denominator will generate an invalid number

I’m just substituting ac with b and the result would be b^3=b^3

Yes when you substitute you will get the same value

How bro?

We never remove a variable from any equation. We only tend to do so when we are sure that variable is not equal to zero.

if you substitute ac=b,it means it is always the case because question asks what *must* be true. ac can be equal to b, but it’s not must. Suppose ac=1 and b=0, it satisfies the above condition, but ac is not equal to b

Hello Everyone, has anyone given the GMAT exam & scored a Q49-Q51 I just wanted to know how difficult are the difficult questions for quants. I have the E-gmat portal and was skimming through the quant section and the difficult questions seemed pretty daunting and very time consuming. Is that the case in actual GMAT as well ?

I also found it difficult and confusing. Sometimes, it seems the question could be solved differently in easier way. I assume my basic is poor.

this is the formula for finding total number of factors if a^n and b^m are the factors then the formula for finding total number of factors would be (n+1)*(m+1)

Use it as in ?? The prime factors of 441 are 3*3*7*7 which 3^2 *7^2 from the above forumula of finding total factors (2+1) * (2+1) that would be 9. So total factors of 441 are 9

oops, sorry, I sent a picture with the formula so you can better understand it but the file is probably too big

but you can see it here for example: https://www.amansmathsblogs.com/factor- ... ny-number/ (skip the text and go directly to the middle of the page where you’ll see big red rectangle

The question is a MUST be true and not a COULD be true. So go for the answer choice which will always be true and not partly true

1) n -8, every number that comes in the range given above will be greater than -8 so that’s our answer.
4) this is a common trap answer, here you’ve basically switched signs i.e multiplied it by -1, but we didn’t change the value of n here, it’s hould have become -1, we also didn’t add the equal to sign. So here value of n can be something like -9,-8, -7 which do not come within the range given in the question. So this is also wrong.
5) as we can see, we already have the answer as option 3
