The expression is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=3c560d98c9fe101a760687ea120408b5.png\")
To simplify the expression follow the order of operations: (PEMDAS)
\1. Evaluate the expressions inside Brackets/Parenthesis (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”![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
First operation is parenthesis.
\(Evaluate powers: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=f6d9f57e726e752ea1cf35d87a50010a.png\")
