Given that \(š„^š¦ < 0\), this implies that
QA Though there are certain restrictions on the possible values of š¦ , for the expression \(š„^š¦\) to be negative, base š„ should be negative. Hence, Quantity A is negative.
QB We can observe that for \(š„^š¦\) to be negative š¦ cannot be even. However, it can be odd or in certain cases a fraction, (as even power always gives nonnegative answer), but nothing about the sign of š¦ can be concluded. Hence, Quantity B can be positive or negative.
D is the answer. Very tricky question to solve rather conceptually
