We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
1. Q^Q=Q^3 so Q=3? How does prime root information change things? 2. Q^2 = 3^2. Q = +-3 NOT SUFF.
I agree with A, what would be an example of a prime root anyway?
Hey rayn, in the first statement we have an equation .
So it is going to have certain number of roots.
One of the roots must be prime........... _________________
OK - so I dug around to see if prime numbers can be negative and there are two answers to this question: basically in lower level math (high school etc... prime numbers cannot be negative but in highler level complex math they can be. I think GMAT assumes PRIME numbers not to be negative no? _________________
