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 a = 3, c = $\"\"$ , d = $\"\"$ )

$\"\"$

Simplify the expression uisng order of operations (PEMDAS).

Since there are no parentheses first operation is evaluating powers.

$\"\"$ (Evaluate power: $\"\"$ )

$\"\"$

Next operation is multiplication.

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

Next operation is division.

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

$\"\"$

The value of the expression is $\"\"$ .
