Question

write the following in expanded form 30.807
8370.705

Answer 1

expanded form of 30.807  $=3\times10^{1} +0\times10^{0} +8\times10^{-1} +0\times10^{-2} +5\times10^{-3}$

and 8370.705 $=8\times10^{3} +3\times10^{2} +7\times10^{1} +0\times10^{0} +7\times10^{-1} +0\times10^{-2} +5\times10^{-3}$

Step-by-step explanation:

Expanded form of

$30.807=3\times10 +0\times1 +\dfrac{8}{10} +\dfrac{0}{100} +\dfrac{7}{1000}$

    $=3\times10^{1} +0\times10^{0} +8\times10^{-1} +0\times10^{-2} +5\times10^{-3}$

and expanded form of $8370.705=8\times1000+3\times100+7\times10+0\times1+\dfrac{7}{10} +\dfrac{0}{100} +\dfrac{5}{1000}$

 $=8\times10^{3} +3\times10^{2} +7\times10^{1} +0\times10^{0} +7\times10^{-1} +0\times10^{-2} +5\times10^{-3}$
