$${\frac{{{\mathtt{10}}}^{{\mathtt{6}}}}{{{\mathtt{10}}}^{{\mathtt{7}}}}}$$
$${\frac{{{\mathtt{10}}}^{{\mathtt{6}}}}{{{\mathtt{10}}}^{{\mathtt{7}}}}}$$
also, if you just think about it for a moment. You have got 6 tens on the top and 7 tens on the bottom when you cancel you will be left with just 1 ten and it will be on the bottom. The top cancels out to 1
$$\frac{10^6}{10^7}=\frac{10*10*10*10*10*10}{10*10*10*10*10*10*10}=\frac{1}{10}$$
Also as CPhill said
$$\frac{10^6}{10^7} = 10^{6-7}=10^{-1}$$
therefore
$$10^{-1}=\frac{1}{10}$$

Remember the rule of exponents here...... an / am = an-m
So ...if I had...... 56/52 ...it would equal........ 56-2 = 54
Now...see if you can do yours, based on this....if not.....let me know.....
