Answer 2

Answer: 0.001

Because the numerator and denominator both have 4 as a term, they can cancel each other out. This leaves the fraction as $\frac{10^{-6} }{10^{-3} }$. When dividing terms with exponents, the exponents should be subtracted. -6-(-3)=-3. Because the term is $10^{-3}$, it needs to be changed into a fraction, so the exponent is positive. This would equal $\frac{1}{10^{3} }$. This equals 1/1000, which is 0.001.
