Exponents..again

1. 2+2+2^2+2^3+2^4+2^5+2^6+2^7+2^8 =?

What would be the best approach to handle 2.?

Sorry for these silly questions..:(

Dear all, Would just like to see what strategy everybody had for approaching an SC question. I currently utilize a "list-check" approach and check the answers one by one e.g. 1. S-V agreement ok? 2. Parallel? 3. Pronoun reference correct? 4. Modifiers in position? 5. Tense correct? 6. Comparisons ma...

Thanks Kolaveri.

Would it be correct to say "which" more often than not will precede a working verb like "were"?

Thanks Jim - I'm guessing that to judge whether the clause is essential or non-essential will depend on what the sentence is trying to say as a whole?

I.e. Which/That usage is very much a judgmental call

That vs. Which strategy

Dear all, Just wanted to see how many different strategies or rather, general "rules of thumb" there are out there for deciding whether "which" or "that" should be used in any given sentence. Personally; I like to think of "which" as introducing a subordinate clause that modifies the noun preceding ...

Isosceles trick

Not sure if I'm missing something here but... If triangle RST is an isosceles, what is angle R? 1) angle T = 100 2) angle S = 40 I thought for an isosceles, if you knew the middle angle; [180-middle angle] /2 would be each remaining angle no? Apparently the answer is NOT choice D.... Sorry I know it...

Redundant primes

J has 2 factors, 12 and 10 12 (3,2,2) 10 (5,2) Is 24 a factor of J? Answer: "J is divisible by 12 and 10, its prime factors include 2,2,3,5 but only TWO 2's because the 2 in the prime factorization of 10 may be REDUNDANT i.e. same 2 as on of the 2's in the prime factorization of 12" and thus because...
