what is 0.09/3*10^4*2*10^-9

$${\frac{{\mathtt{0.09}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{4}}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{9}}} = {\mathtt{0.000\: \!000\: \!6}}$$

OR

$${\frac{{\mathtt{0.09}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{4}}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{9}}}$$

$${\frac{{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{0.09}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{4}}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{9}}}$$

$${\mathtt{0.06}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{5}}}$$

$$6\times 10^{-2} \times 10^{-5}\\

6\times 10^{-7}\\

0.0000006$$

.

first drag 10^-9 to the top since its the same as 10^9

so .09*10^9/3*10^4*2

then get rid of 10^4 on the bottom by removing 4 from the 10^9 on top

so. .09*10^5/3*2

now just multiply .09 and 10^5 =9000 on top and 3*2 to 6 on bot

so 9000/6 and then divide to 1500

The answer is 1500
