If you mean: 2^3 times 2^7 times 2^3 then it equals 8192
2^4 * 2^3 16 * 8 128
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
2 x 10-3 = 0.002
27 X 23 = 210 =1024
2 times 3 to the power of 2 is equal to 18.
The GCF of 108 and 144 is 36, or 2^2 x 3^2

If you mean: 2^3 times 2^7 times 2^3 then it equals 8192

It is correct only for the first one. The second one should be 3 to the power 2 times 2 times 5.
2 times 3 to the second power equals to 2x9 or 18 2 to the second power times 3 equals to 4x3 or 12 therefore the least common factor is 2.

GCF is 60
