What will come in place of the question mark (?) in the given question? $$( 8 * 16 \div 256 * 512 ) \times \frac{1}{2^?} = 1$$

Explanation

Expression : $$( 8 * 16 \div 256 * 512 ) \times \frac{1}{2^?} = 1$$ => $$(\frac{128}{256} \times 512) \times \frac{1}{2^x} = 1$$ => $$(128 \times 2) \times \frac{1}{2^x} = 1$$ => $$\frac{256}{2^x} = 2^0$$ => $$2^{8 - x} = 2^0$$ => $$8 - x = 0$$ => $$x = 8$$
