Find the missing factor. write your answer in exponential form. 8^-9=8^-6 =?
This isn't as difficult as it seems
8^(-9) = 8^(-6) + ? can be written as
1 / 8^9 = 1/8^6 + ? subtract 1/8^6 from both sides
1 / 8^9 - 1 / 8^6 = ? getting a common demoninator on the right we have
[ 1 - 8^3 ] / 8^9 = ?
-511/ 134,217,728 = ?
