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 \"\"

\

\"\"                         (Substitute \"\")

\

Simplify the expression using order of operations (PEMDAS)

\

In the given expression there are no grouping symbols,first operation is evaluate powers.

\

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

\

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

\

Next operation is multiplication.

\

\"\"                         (Multiply: \"\")

\

\"\"                            (Multiply: \"\")

\

\"\"                                  (Multiply: \"\")

\

\"\"

\

Next operation is addition.

\

\"\"                                  (Add: \"\")

\

Next operation is subtraction.

\

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

\

Next operation is division.

\

\"\"                                       (Divide: \"\")

\

\"\"

\

The value of the expression is 3.12.
