Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Use the table below to find $w'(\var{b})$ if $w(x)=h(g(x))$ .

$x$	$g(x)$	$g'(x)$	$h(x)$	$h'(x)$
1	3	$\var{gp[0]}$	3	$\var{hp[0]}$
2	1	$\var{gp[1]}$	2	$\var{hp[1]}$
3	2	$\var{gp[2]}$	1	$\var{hp[2]}$

$w'(\var{b})=$ Unnamed gap

Advice

When $n$ is positive, we multiply $10$ by itself $n$ times,

$\text{e.g. } 10^3 = 10 \times 10 \times 10 = 1000 \text{ .}$

When $n$ is negative, we can think of $10^{-n}$ as $\frac{1}{10^{n}}$ ,

$\text{e.g. } 10^{-3} = \frac{1}{10^3} = \frac{1}{1000} = 0.001\text{ .}$

When $n = 0$ :

$10^{0} = 1 \text{ .}$

Generally, we can think of $10^n$ as a number in standard form $1 \times 10^n$ . Then $n$ always tells us the number of decimal places to move the decimal point in $1.0$ , for example

$10^{-3} = 1.0 \times 10^{-3} \text{ and since } n = - 3 \text{, we go } 3 \text{ places back as follows: } 1.0 ⇒ 0.1 ⇒ 0.01 ⇒ 0.001 \text{ .}$

A complete table of powers of ten for $n$ from $-6$ to $6$ is:

$n$	$10^n$
$-6$	$0.000001$
$-5$	$0.00001$
$-4$	$0.0001$
$-3$	$0.001$
$-2$	$0.01$
$-1$	$0.1$
$0$	$1$
$1$	$10$
$2$	$100$
$3$	$1000$
$4$	$10000$
$5$	$100000$
$6$	$1000000$
