tankabanditka [31]

So, we know these three things:

1. \text{ } a^b*a^c=a^{b+c} \\
2. \text{ } (a^b)^c=a^{bc}

So, we have:

12^{11}*(12^2)^4=\\
12^{11}*12^{8} =\\

Can someone help me asap
dmitriy555 [2]

Answer:

2) 3 : 15 = 1 : 5

3) 22 : 38 = 11 : 19

4) 2 : 5 = 26 : 65

Step-by-step explanation:

2) 5, 3, 1, 15

3 : 15 = 1 : 5

If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.

3) 19, 22, 11, 38

22 : 38 = 11 : 19

If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.

4) 65, 2, 26, 5

2 : 5 = 26 : 65

If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.

Hope this helps and stay safe, happy, and healthy, thank you :) !!
