Given the question in the question tab, the following are the solution steps to answer the question.

STEP 1: Write the given expression


3x-4xy^2

STEP 2: Substitute the given values for x and y into the expression.


\begin{gathered} x=-1,y=2 \\ 3x-4xy^2=3(-1)-4(-1)(2^2) \\ \Rightarrow-3-(4*-1*4) \\ \Rightarrow-3-(-16) \\ -*-=+ \\ \Rightarrow-3+16 \\ \Rightarrow13 \end{gathered}

Hence, the evaluation of the exponent expression gives 13
