The expression is.

Write the expression with in the division form 

Substitute value of x = 4 and y = 3.

Then 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 pf operations is turned into phrase

“Please Excuse My Dear Aunty Sally”

First operation is evaluating the expression with in parenthesis.

                                (Add:  )

Next operation is multipling

                                   (Multiply:  ).

Next operation is adding

                                          (Add:  ).

Next operation is division

                                                   (Division:  ).

The value of given expression is .
