The expression is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=dd781dcd7f74b461bac1d0e4382750b4.png\")
Substitutive the value of x = 3 and z = 5
\The expression is![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c90d67aa082f2751e60e19294bc2105e.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 pf operations is turned into phrase
\“Please Excuse My Dear Aunty Sally”

First operation is evaluating the expression is Powers
\= (Powers:![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=bbbf7bb48fb89fe4a4d089bb2ac04715.png\")
)
![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=6bc299a9e59d82cad3a3faaf307891e4.png\")
(Multiply:![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=34929dcc9f909064c88a9799fe5502e3.png\")
)
Next operation is subtraction
\=26 (Subtract: 35-9=26)
\\
![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The value of given expression is 26.
