\n\\[\\text{e.g. } 10^3 = 10 \\times 10 \\times 10 = 1000 \\text{ .}\\]
\nWhen $n$ is negative, we can think of $10^{-n}$ as $\\frac{1}{10^{n}}$,
\n\\[\\text{e.g. } 10^{-3} = \\frac{1}{10^3} = \\frac{1}{1000} = 0.001\\text{ .}\\]
\nWhen $n = 0$:
\n\\[10^{0} = 1 \\text{ .}\\]
\nGenerally, 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
\n\\[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{ .}\\]
\nA complete table of powers of ten for $n$ from $-6$ to $6$ is:
\n$n$ | \n$10^n$ | \n
---|---|
$-6$ | \n$0.000001$ | \n
$-5$ | \n$0.00001$ | \n
$-4$ | \n$0.0001$ | \n
$-3$ | \n$0.001$ | \n
$-2$ | \n$0.01$ | \n
$-1$ | \n$0.1$ | \n
$0$ | \n$1$ | \n
$1$ | \n$10$ | \n
$2$ | \n$100$ | \n
$3$ | \n$1000$ | \n
$4$ | \n$10000$ | \n
$5$ | \n$100000$ | \n
$6$ | \n$1000000$ | \n
