INVESTMENT rank

→ designation of multiple forms of short repeated with the same multiplier factors. Each product can be repeatedly written or presented in a brief notation by using the exponential notation, or have an important position.

Example:
• The form of repeated multiplication axaxaxa, written in short notation with numbers or have an important position as the exponential notation a4, "a4" read a four-grade.
• The form of repeated multiplication of 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6, is written in short notation with numbers or have an important position as the exponential notation 69, "69" read six ninth-grade.

Nature rank on the floor unanimously positive.
If a and b real numbers and n, p, q and the original, then apply:
1. Distributif rank nature of the multiplication.

Example:

(2 x 3) 3 = 23 x 33
= 8 x 27
= 216
2. Distributif rank nature of the division.

Example:

(4: 2) 2 = 42: 22
= 16: 4
= 4
3. Between the nature of multiplication rank with the same number.

Example:

103 x 104 = 103 + 4

= 107

4. Nature of the division between the have an important position with the same number.

Example:

74: 72 = 74 - 2

= 72
= 49
5. Nature of the promotion have an important position.

Example:
(22) 3 = 22 x 3
= 26
= 64
