Multiplying and dividing exponents any one knows the full paper

Here is a couple:

1)  4^2 * 4^2 = 4 ^(2+2) = 4^4 = 256     You try #3

4) is   2¹ * 2² *2²    and solved similarly   #2 is also similar    4¹  * 4² 

5)  2n^4 * 5 n^4 = 10 n^6      You try  #6

1: is 4 to the power of 4.

2: is also 4 to the power of 4

3: is 3 to the power of 4

why? because when multiplying th same numbers and exponents, add the exponents:

2 to the power of 2 + 2 to the power of to =  2 to the power of four.      and 2 to the power of four  = 8

2) is   4³
