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:


\begin{gathered} -3\lbrack(-7^2)-16\rbrack+(4)/((2)/(5))=-3\lbrack-49-16\rbrack+(4)/((2)/(5)) \\ =-3\lbrack-65\rbrack+(20)/(2) \\ =-3(-65)+10 \\ =195+10 \\ =205 \end{gathered}

Therefore the answer is 205.
