the awnser to your question is -8.
No, it's One-quarter. 21 = 2, 20 = 1, 2-1 = 1/2, 2-2 = 1/4. Each reduction of 1 in the power gives a result half of the previous term.

What is 2 to the 3rd power times 2 to the 2nd power times 2 to the negative 1 power?
2 cubed )2^3) is 8, 2 squared (2^2) is 4, and 2 to the negative 1 power is done by thinking of a fraction. We know that any whole number can be made into a fraction, like 2 is 2/1. Well when we have negative exponents, these are solved by putting those numbers to negative powers into the bottom. So (2^-1)/1 would be changed to 1/(2^1) or 1/2. So if we now multiply these three numbers, we get 16.
