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 R>0, and c,d and e are each different negative integers, what is the smalest that c could be?
You are assuming that R is an interger >0. But in the problem c,d,e are defined as negative intergers. R may not be an integer - isn't it?
If we take, R=2√3; c=-12, d=-7, e=-5 then, c+d+e=-24
so, R^(c+d+e) = (2√3)^-24 = 12^-12 That's why I think answer is A. Feedback pls.
But how can you 'guess'tify R to be a non-integer
Even if c+d+e = -24 , why C is -12 , why can't it be -22 ?
Per the question C, D and E need to be -negetive integers , So each one of them may atmost be -1.
So this gives us C to be -22 ?
I feel (A) should be - 22 (may be a typo ).
