The issue I can't figure out with this problem is: Why can't we assume that Statement 1 will always yield a positive number? Here's my logic: Since sqrt(x^2) equals the absolute value of x, why can't we assume that sqrt(x^4), which is the same as sqrt(x^2*x^2), will also always be positive? sqrt(x^...

What is the value of x?
What is the value of x? (1) sqrt(x^4) = 9 (2) sqrt(x^2) = -x The issue I can't figure out with this problem is: Why can't we assume that Statement 1 will always yield a positive number?

Hi Suzee, essentially, the first question is a "yes/no" question while the second is a "value" question. On the GMAT, you'll see about 15 DS, about 5 of which will be yes/no, and 10 of which will be value. For yes/no questions, a range of values can qualify for sufficiency while...

Confused about rules for absolute values - help!
Hi guys - I'm having trouble understanding the rules around solving absolute value questions. Can someone help me? OK, so first consider this question from MGMAT: Is x > 0? (1) |x + 3| = 4x – 3 (2) |x + 1| = 2x – 1 The answer is D; each statement alone is sufficient. The answer explanation says ...

Thank you everyone for all your replies! I truly appreciate it. I understand this question now - as some of you guys mentioned, you can't just subtract one ratio from the other. I also think I misunderstood the question in general.
Thanks again. You guys are the best!

Ratio question: Yankees and Dodgers
Hi, I have a question from BTG's Smart GMAT practice. Every person in a certain group is either a Dodgers fan or a Yankees fan, but not both. The ratio of Yankees fans to Dodgers fans is 5 to 3. If 22 Yankees fans change teams to become Dodgers fans, the ratio of Dodgers fans to Yankees fans will be...

st 1: x/6=q+2/6; x = 6q+2; 6q+2 / 3; r =2/3
st2: x/15=q+2/15; x=15q+2; 15q+2 / 3; r = 2/3

This is really helpful - was wondering about the algebraic approach. Thank you!!

What is the remainder?
What is the remainder when the positive integer x is divided by 3?
(1) When x is divided by 6, the remainder is 2.
(2) When x is divided by 15, the remainder is 2.
How do you determine remainders here?
(Got this from mba.com prep test.)
Thank you!

I think you're main confusion is on order of operations if it was (2^3)^2, then, yes, your answer would be right but in this case it's not that way. it's 2^3^2 which by order of operation you square the 3 first making the equation simplify to 2^9 Ohh, OK. That makes sense why I kept getting the wro...

Thanks for the quick reply! I'm still a bit confused because I thought to calculate an exponent of an exponent, you multiply the exponents? For example, (2^3)^2 = (2*2*2)(2*2*2) = 2^6Gmat_War wrote:(4-1)^2= 3^2=9
Therefore 2^9/2^(1)
=>2^(9-1)=2^8
