The answer is:  45 * 10 ⁻¹¹ .
___________________________________________

Explanation:
____________________________________________
Given:   (9 * 10⁻⁵) * (5 *10 ⁻⁶) ;   Simplify.
____________________________________________
 (9 * 10⁻⁵) * (5 *10⁻⁶)  =

9 * 5 * 10⁻⁵ * 10⁻⁶ = 

(9 * 5) * 10⁻⁵ * 10⁻⁶ 

45 * 10⁻⁵ * 10⁻⁶  ;   
______________________________________
Note the following property of exponents:

xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾ ;

As such, 10⁻⁵ * 10⁻⁶ = 10⁽⁻⁵ ⁺ ⁻⁶) = 10 ⁻¹¹ ;
______________________________________
So;  45 * 10⁻⁵ * 10⁻⁶ 

           =  45 * 10⁻¹¹ .

What is the value of K in the equation 8 + 2k = 4k + 4
11111nata11111 [884]
8+2k=4k+4
8-4=4k-2k                   I placed the like terms on each side.
4=2k                           Simplify
4/2=k                          Leave the variable a side

The product of two irrational numbers is. Rational
Snowcat [4.5K]

Answer:

So the statement:

"The product of two irrational numbers is rational." is false.

Step-by-step explanation:

The product of two irrationals can be irrational or rational.

Example:

\sqrt{2} \cdot \sqrt{2}=2

\sqrt{2} is irrational but when you multiply it to itself the output is rational.

Example:

\sqrt{2} \cdot \sqrt{3}=\sqrt{6}

\sqrt{2} \text{ and } \sqrt{3} are irrational and when you multiply them you get an irrational answer of \sqrt{6}.

So the statement:

"The product of two irrational numbers is rational." is false.

1. Each term in this polynomial has a common factor of 3x^3:

12x^6-9x^4+18x^3=3x^3(4x^3-3x+6)

2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.

(3x-5)(2x^2+7x-3)=3x(2x^2+7x-3)-5(2x^2+7x-3)

(3x-5)(2x^2+7x-3)=(6x^3+21x^2-9x)+(-10x^2-35x+15)

(3x-5)(2x^2+7x-3)=6x^3+11x^2-44x+15

3. You can use the same approach as in (2), or recall that (a+b)^2=a^2+2ab+b^2:

(5x-4y)^2=(5x)^2+2(5x)(-4y)+(-4y)^2

(5x-4y)^2=25x^2-40xy+16y^2

4. Recall that a difference of squares can be factored as a^2-b^2=(a-b)(a+b). So

(2x^2-7)(2x^2+7)=(2x^2)^2-7^2

(2x^2-7)(2x^2+7)=4x^4-49
