\

The expression is \"\".

\

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”\"\"

\

Evaluate the expressions inside Brackets

\

First operation is evaluate powers.

\

\"\"            (Evaluate powers: \"\")

\

Next operation is subtraction.

\

\"\"                          (Subtract: \"\")

\

Next operation is division.

\

= 4.5                            (Divide: \"\")\"\"

\

The simplified expression value is 4.5.
