Answer:

The correct number of basic operations that exist in mathematics is four (addition, subtraction, multiplication and division) because the definition of an operation is the carrying out of a task by the application of principles and these four operation are arithmetic operations that have precedence rules or order of operations, such that we must first multiply or divide before adding or subtracting

Division is different from simply multiplying by a fraction because in Euclidean division, the result is a quotient and a remainder, which shows that division can yield more than one result while multiplication yields a single result

For subtraction and addition, one of the differences is that subtraction cannot be simply commuted

a - b = -(b - a)

Subtraction is non-associative;

a - b - c when arranged as (a - b) - c and a - (b - c), can yield different results depending on operation order which is unlike addition

Therefore, the four basic operations in mathematics are addition, subtraction, multiplication and division

Rewrite each expression as a sum or difference of terms. (i) (x+3)(x-3) (ii) (x^2-3)(x^2+3) (iii) (x^15+3)(x^15-3) (iv) (x-3)(x^

Answer:

All the answers are given below.

Step-by-step explanation:

(i) (x+3)(x-3) =x² -3² =x² -9 {Since (a+b)(a-b) =a² -b²}

(ii) (x²-3)(x²+3) =(x²)² -3² = $x^{4} -9$ {Since (a+b)(a-b) =a² -b²}

(iii) $(x^{15} +3)(x^{15}-3) =(x^{15} )^{2}-3^{2} =x^{30} -9$

(iv) (x-3)(x²-9)(x+3) =(x²-9)(x²-9)=(x²-9)²= $x^{4}-18x^{2} +81$ {Since, (a-b)² =a²-2ab+b²}

(v) (x²+y²)(x²-y²) = (x²)² -(y²)² = $x^{4}-y^{4}$

(vi) (x²+y²)² = $x^{4}+2x^{2} y^{2} +y^{4}$ {Since (a+b)² =a²+2ab+b²}

(vii) (x-y)²(x+y)² =(x²-y²)² = $x^{4} -2x^{2} y^{2}+y^{4}$ {Since (a-b)² =a²-2ab+b² and (a+b)(a-b) =a²-b²}

(viii) (x-y)²(x²+y²)²(x+y)² =(x²+y²)²(x²-y²)² = $(x^{4} -y^{4} )^{2} =x^{8}-2x^{4} y^{4} +y^{8}$ (Answer)

A Japanese beetle has length between 0.3 and 0.5 inches.Find two lengths that are within the given span. Write them as fraction

Wittaler [7]

A Japanese beetle’s length are equals to
=> 0.3 inches
=> 0.5 inches

Now let’s find the length that is between the span of the two given length:
But before that let’s convert the 2 given numbers in decimal points to fraction:
=> 0.3 = 3/10
=> 0.5 = 5/10

Find the fraction between the given 2 numbers:
=> 0.3
=> 0.4
=> 0.5

Therefore the number we are looking 0.4
=> 0.4 = 4/10
Now, we have the complete length of Japanese beetles, the 0.3, 0.4 and 0.5
