156*10-7 = 0.0000156 or as 1.56*10-5 in scientific notation
156x107 is 1.56x109
7 to the power of 5 is written as 75
7 to the second power
7 to the power of 3 is: 7 x 7 x 7 = 343 Another way to write it is: 7^3 = 343
You can write 49 as a power by expressing it as (7^2), since (7 \times 7 = 49). Alternatively, it can also be written as (49^1), since any number raised to the power of 1 is itself. Thus, the primary representation is (7^2).

To write 7x7x7x7x7x7 as a power of seven. (answer is 117649) or you could write 7 with a little 6 on top on the right hand side. This indicates that it is to the power of 6 (the number up the top, in this case 6, is called an index and the normal number is called the base.
