Can you help me please

Answer:

Step-by-step explanation:

Here we a given a rule

It say

$x(y$ ÷ $3)^2$

And we are given the values of x and y as

x=4 and y = 9

Let us replace them in the rule we are provided with

$4(9$ ÷ $3)^2$

Applying DMAS rule, which says, first Division ollowed by Multiplication addition and then subtraction .

We first divide 9 by 3

9÷3 = 3

Hence

$4(9$ ÷ $3)^2 = 4(3)^2$

Now we square first

$3^2 = 3 \times 3 = 9$

$4(3)^2 = 4 \times 9$

$4(3)^2 = 36$

Hence our final answer will be 36
