Answer:

x⁶ +30x⁵ +375x⁴ +2500x³ +9375x² +18750x +15625

Step-by-step explanation:

The expansion is the sum of C(6, k)·x^(6-k)·5^k for k=0–6, where ...

... C(6, k) = 6!/(k!(6-k)!)

For k = 0–6, C(6, k) = {1, 6, 15, 20, 15, 6, 1}

Then the expansion is ...

... x⁶ +6·5¹·x⁵ +15·5²·x⁴ +20·5³·x³ +15·5⁴·x² +6·5⁵·x +5⁶

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
