Which expressions are equivalent to 2^5x2^4? check all that apply. 2^9 2^20 2x2^9 2^10x2^2 2^-2x2^11 (2x2x2x2x2)(2x2x2x2)

Hello!

You can put all of these into a calculator and see if the equation the original equation.



Then you do 2^9 which equals 512

So 2^9 is one of the answers

Then 2^20 = 1048576

Since it does not equal 512 it is not one of the answers

2 * 2^9 = 1024

2^10 * 2^2 = 4096

2^-2 * 2^11 = 512

(2*2*2*2*2)(2*2*2*2) = 512

So the answers are:

2^9
2^-2 * 2^11
(2*2*2*2*2)(2*2*2*2)

Hope this helps!

128 over 10 because this as a fraction is 12 and 8/10 so then times 12 by 10 and you get 120 then add 8 and then you get 128 and put it over 10
