In each of the questions given below which one of the five figures on the right shoulde come after the problem figures on the left, if the sequence were continued ?





What will come in the place of question mark (?)
$$(a)^{c}\times(b)^a\times?=0$$, if a, b, c are not equal to 0.
$$((a)^2)^?=(a)^6$$
$$?\times(\mid a \mid \times \mid b \mid)=-ab$$, where a, b > 0
$$(c)^0\div b=?$$
$$((a)^b)^?=1$$, where a $$\neq$$ 1 and b $$\neq$$ 0.
