Well, 4 times 4 times 4, well, that's just equal to 4 to the third.

4 x 4 is 16 x 4 is 64.

1 is the same thing as 4 4, and then you have three more fourths, so 4 4 plus 3 4 will give you 7 4.

Four to the first is four, four to the second is 16 and we want to multiply 16 times 4,

7 4 is 4 4 with 3 4 left over.

Negative 4, negative 4.

And then plus 4, so f of minus 4 is 4.

4 was minus 4, so now it becomes 4.

4 plus 2 times minus 2, that's 4 minus 4, that's 0.

So that's 1 4, 2 4, 3 4, 4 4, which is a whole, 5 4, 6 4, 7 4, 8 4, which is equal to 2 wholes.

4 times 4, 16, minus 4 times 4, 16, right.

If I would ask you what negative four to the third power is, well that equals negative four times negative four times negative four.

I'm tempted to do some of this in my head, but we've gotten so far I don't want to make mistakes. So 4 goes into 12 three times. 3 times 4 is 12.

So this is, 4 plus 4 is 8, 4 times 4 is 16.

But when x is equal to 4, you stick 4 in here, you get 4 minus 4.

Or ten fourths minus three fourths is equal to seven fourths.

6b 7a

So times 4.

This right here is 4 4.

4.3.2.4 Existing paragraph 4.3.2.4 becomes new 4.3.2.4.1.

Well, 4 times 4, times 4 is equal to 64, or 4 to the third is equal to 64, which means that 4 is equal to 64 to the 1 3.

That makes sense because we're essentially saying what's negative 4 times itself three times, so it's like negative 4 plus negative 4 plus negative 4, which is negative 12.

Notice, 7 4 is 4 4 with 3 4 left over.

2 and 1 4 divided by 1 and 3 4 is the same thing as 9 4 divided by 7 4.

Then c, 4 negative 4. x is equal to 4. y is equal to negative 4.

2 a squared to fourth power is going to be equal to 2 to the fourth power, colour coded, 2 to the fourth power times a squared to the fourth power times a squared to the fourth power and then all of that over 3 b to the fifth to the fourth power, that's going to be 3 to the fourth power, 3 to the fourth power times b to the fifth, times b to the fifth, to the fourth power, times b to the fifth to the fourth power

So that's x to the minus 4. x to the minus 4 is 1 over x to the 4.

Notice that two to the fourth is equal to four times four, right?

So this is going to be 4 so XZ ends up being 4 that is 4

Block 3, 4 4

Block 4, 4 8

Introduction 1 4

Introduction 1 4 4

And f of minus 4 is equal to 4.

So four plus four is eight.

Negative 6 comma negative 4.

4 minus 0 is 4.

And then 8 minus 4 is 4.

What is 4 4?

This 4 by 4, you get 1.

So we have minus 4 times a 2 times a minus 4.

It's equal to 4.

And the reason why this makes sense is 1 is 4 4, or 1 is 4 times 1 fourths, right?

Consequential changes in 6.4.5.4.1(c)(ii), 6.4.5.4.2(c), 6.4.5.4.4(c)(ii), 6.4.5.4.5(b)(ii) and 6.4.7.14(b).

Well, that would just be equal to 4 times 5 times 4 times 5 times 4 times 5, right, which is the same thing as 4 times 4 times 4 times 5 times 5 times 5, right?
