OpenStudy (anonymous):

ok this is the last one i got A or D

rishavraj (rishavraj):

no need to be sorry......

rishavraj (rishavraj):

see a^-1 = 1/a and 1/(a)^-1 = a...

OpenStudy (anonymous):

So it is D?

OpenStudy (anonymous):

because -4*-4*-4*-4 is positive 256

rishavraj (rishavraj):

no thats not the reason....

OpenStudy (anonymous):

rishavraj (rishavraj):

\[1/4^{-4} = 4^{4}\]
