Thank you for using the timer!
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:
If q is an odd integer greater than 1, What is the value of (-1)^(q+1) A) -2 B) -1 C) 0 D) 2 E) cannot be determined
q is an odd integer>1 --> q+1 is even integer>2. -1 in even power is 1. Negative number (not necessarily integer) in odd power - negative and in even power positive. -1 in odd power =-1; -1 in even power=1.
So answer is 1. No correct choice.
Maybe there is a typo and the question says "q is an even integer"? If so answer would be -1. _________________
