\begin{gathered} We\text{ are asked to simplify the following:} \\ 2^(-3)*2^(-4) \\ We\text{ know that whenever we have numbers with the same base \lparen in this case 2\rparen multiplied by each other,} \\ we\text{ are to add the relevant exponents and keep the base.} \\ Adding\text{ -3 + -4 = -7} \\ We\text{ then have 2}^(-7) \\ Lastly,\text{ we know that when we have a number with a negative exponent, this is the same as the inverse of that number.} \\ 2^{-7\text{ }}=\text{ }(1)/(2^7) \end{gathered}

The correct option is option number 2.
