E. $$0.0000675 * 10^3$$

Let's travel thru options:-

A. $$67.5*10^{−3}$$ ; shift the decimal by 3 positions to the left, we have 0.0675

B. $$6.75*10^{−2}$$ ; shift the decimal by 2 positions to the left, we have 0.0675

C. $$0.675 * 10^{−1}$$ ; shift the decimal by 1 positions to the left, we have 0.0675

D. $$0.00675 * 10^2$$ ; shift the decimal by 2 positions to the right, we have 0.675

E. $$0.0000675 * 10^3$$; shift the decimal by 3 positions to the right, we have 0.0675

Ans. (D)
