Answer 2

1. 2^5*2^7=2^(5+7)=2^12

2. 8^2 : 2^4= (2^3)^2 : 2^4=2^(3*2) : 2^4=2^6:2^4=2^(6-4)= 2^2

3. 3^2*2^2=(3*2)^2

4. 27^3:3^4=(3^3)^3 : 3^4=3^9 : 3^4= 3^5

5. 100^3:2^6*5^6=(10^2)^3: (2*5)^6=10^6: 10^6=10^(6-6)  = 10^0=1

6. 4^3:2^2=(2^2)^3=2^6:2^2=2^4

7. (1/2)^2 *4=1/2^2 * 4 =1/4*4=1

8. (2/3)^4* (3^3/2^4)=2^4*3^3/3^4*2^4=1/3

9. (1/7)^3*49=1/7^3 * 7^2= 1/7

10. 1/2^3 * 2^2 = 2^2/2^3=1/2
