### Smart Math exponential number and Operations powers of integer arithmetic

Label:
Easy Math

**Smart Math in**

**exponential number**.

quadratic terms of a number. Squared or the square of a number is multiplying a number by the number itself.Furthermore, the powers of a number means multiplying repeated with the same number.

Note the following powers of prime number 2.

2 ² = 2 x 2 (2 ² read 2 squares or 2 to the power 2)= 42 ³ = 2 x 2 x 2 (2 ³ read 2 to the power 3)= 8

Smart Math Solution:

a. 9 ² = 9 x 9 = 81b. (-6) ³ = (-6) x (-6) x (-6) = 36 x (-6) = -216c. -5 = - (5 x 5x 5 x 5) = -625d. (-10) 4 = (-10) x (-10) x (-10) x (-10) = 10,000 Properties exponential number.

a. Multiplicative nature of the exponential number Note the following rank of integer multiplication.3 ² x 3 ³ = [3x3] x [3x3 x3]Means [3x3] = 2 factors and [3x3x3] = 3 factors So there are 5 factors add up, so be 3x3x3x3x3

b.Nature of the distribution of exponential number Note the following integer division rank.

5 ³: 5 ² = [5x5x5]: [5x 5] the meaning [5x5x5] = 3 factors and [5x 5] = 2 factors So there is 1 factor is reduced, so that a 5

**Smart Math Operation Count Mixed Integer**

In completing integer arithmetic operations, there are two things to note, that1. sign arithmetic operations;2. brackets.If in a mixed integer arithmetic operations are bracketed, workmanship are in brackets should be done first.

If in an integer arithmetic operation there is no parentheses, the process is based on the properties of the following arithmetic operations.1. Operations of addition (+) and subtraction (-) as strong, meaning that operations are located on the left side done first.2. Multiplication (x) and division (:) as strong, meaning that operations are located on the left side done first.3.

Multiplication (x) and division (:) is stronger than the addition operation (+) and subtraction (-), multiplication means (x) and division (:) done first rather than the addition operation (+) and subtraction (-).

Example:

a. 24 + 56 x 42-384 : 12= 24 + (56 x 42) - (384: 12)= 24 + 2352-32= 2376-32= 2,344

b. 28 x (364 + 2,875): (9756-9742)= 28 x 3,239: 14= 90 692: 14= 6,478

c. 80: ((11-7) x (-4))= 80: (4 x (-4))= 80: (-16)= -5

d. (-8 + 5) x (36: (6-9))= -3 X (36 (-3))= -3 X (-12)= 36

Thus example Smart Math exponential number and Operations of integer arithmetic, may be useful for the reader.
