Thanks a ton for quick response. how can b² be negative for a?? That's confusing. Am I missing something very basic here. Please throw some light.

Thanks again!

b^2 is not negative but a can be negative or positive.

If a=-4 and b=2

a^2=b^4

(-4)^2 = 2^4

Similarly if a=4 and b =2

4^2 = 2^4


Here we cannot say for sure, whether a = 4 or -4 for b=2
