Break it up into the numbers and exponents.
x%2810%5E12%2A10%5E8%29%2F%2810%5E7%2A10%5E2%29
%286%2A10%5E12%29%283.2%2A10%5E8%29%2F%281.6%2A10%5E7%29%283%2A10%5E2%29=4x10%5E%2812%2B8-7-2%29
%286%2A10%5E12%29%283.2%2A10%5E8%29%2F%281.6%2A10%5E7%29%283%2A10%5E2%29=4x10%5E%2811%29

%286%2A10%5E12%29%283.2%2A10%5E8%29%2F+%281.6%2A10%5E7%29%283%2A10%5E2%29
what we can cancel her is:

6 and 3 divide both by 3

3.2 and 1.6 divde both by 1.6

10%5E12 and 10%5E7 both divide by 10%5E7;so, you will have

10%5E12%2F10%5E7+=+10%5E%2812-7%29+=+10%5E5, and 10%5E7%2F10%5E7=1

10%5E8 and 10%5E2 both divide by 10%5E2;so, you will have

10%5E8%2F10%5E2+=+10%5E%288-2%29+=+10%5E6, and 10%5E2%2F10%5E2=1

then we have:

%282%2A10%5E5%29%282%2A10%5E6%29

%284%2A10%5E%285%2B6%29%29

%284%2A10%5E11%29
