X to the forth power ÷ 3+9 when x=3

36

Step-by-step explanation:

Ok, so the expression we are given is ÷ 3 + 9.

We know that x = 3, so we need to substitute 3 in as x.

So, now the expression looks like ÷ 3 + 9.

Now we can solve this expression.

First we need to figure out what   is equal to.

1.   = 81

We're left with 81 ÷ 3 + 9.

Next, we need to divide our 81 by our 3.

2.  81 ÷ 3 = 27

Our new expression is 27 + 9.

Last, we need to add our 27 and our 9 together.

3.  27 + 9 = 36

Our answer is 36.

So ÷ 3 + 9 when x = 3 is 36.
