Order of Operations:
\To simplify the expression follow the order of operations: (PEMDAS)
\1. Evaluate the expressions inside the Parenthesis/Brackets (P).
\2. Evaluate Powers/Exponents (E).
\3. Multiply and/or Divide in order from left to right (MD).
\4. Add and/or Subtract in order from left to right (AS).
\A simple technique for remembering the order of operations is turned into phrase "Please Excuse My Dear Aunty Sally"
\
The expression is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=4305a362eeba04b747846b2d767ff784.png\")

(Replace c with ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=2af6e83b0e9af64878f4e8cc8c73d3f5.png\")
)
Since there are no grouping symbols. First operation is evaluate power.
