$${\frac{\left({\mathtt{8.4}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{4}}}\right)}{\left({\mathtt{6}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{3}}}\right)}} = {\mathtt{0.000\: \!000\: \!14}}$$ what is this in standard form and how do you get to it?
+427 If you just mean how to make the web2.0calc calculator give the standard form, just click the = key again and it will give different forms (This is also how you can get it to display it in fraction form).
If you want to be more manual when working in standard form, try dealing with the 10x numbers seperate to everything else.
In this case, you can look at this more like:
$$\left({\frac{{\mathtt{8.4}}}{{\mathtt{6}}}}\right){\mathtt{\,\times\,}}\left({\frac{\left({{\mathtt{10}}}^{-{\mathtt{4}}}\right)}{{{\mathtt{10}}}^{{\mathtt{3}}}}}\right)$$
This gives 1.4 * 10(-4 - 3) = 1.4 * 10-7
Remember: 10x * 10y = 10x+y, and from that you can get 10x ÷ 10y = 10x-y
