To answer this questions we need to remember the order of operations:
• Parentheses (simplify inside 'em)
,• Exponents
,• Multiplication and Division (from left to right)
,• Addition and Subtraction (from left to right)
With this in mind we have:
[tex]\begin{gathered} -3\lbrack(-7^2)-16\rbrack+\frac{4}{\frac{2}{5}}=-3\lbrack-49-16\rbrack+\frac{4}{\frac{2}{5}} \\ =-3\lbrack-65\rbrack+\frac{20}{2} \\ =-3(-65)+10 \\ =195+10 \\ =205 \end{gathered}[/tex]Therefore the answer is 205.
