Help me please I literally don’t understand any of this. I know it’s easy too.

Holigina, this is the solution:

Let's recall that √x = x ^(1/2)

Therefore,

√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)

The correct answer is C. 1

Match each expression written in standard form to the equivalent expression in factored form
den301095 [7]

Answer:

1. 15x^7y^2 + 4x^3 => x^3(15x^4y^2 + 4)

2. 15x^7y^2 + 3x => 3x(5x^6y^2 + 1)

3. 15x^7y^2 + 6xy => 3xy(5x^6y + 2)

4. 15x^7 + 10y^2 => 5(3x^7 + 2y^2)

Step-by-step explanation:

To obtain the answer to the question, first let us factorise each expression. This is illustrated below:

1. 15x^7y^2 + 4x^3

Common factor is x^3, therefore the expression is written as:

x^3(15x^4y^2 + 4)

2. 15x^7y^2 + 3x

Common factor is 3x, therefore the expression is written as:

3x(5x^6y^2 + 1)

3. 15x^7y^2 + 6xy

Common factor is 3xy, therefore the expression is written as:

3xy(5x^6y + 2)

4. 15x^7 + 10y^2

Common factor is 5, therefore the expression can be written as:

5(3x^7 + 2y^2)

Solve by taking the square root I need help understanding steps this is hard for me. ​
Shalnov [3]

Answer:

x= -2 \pm \sqrt{13}

Step-by-step explanation:

Given: 3x^{2} -12x+27= 0

This is a quadratic equation.

3x^{2} -12x+27= 0

Taking common 3 from the equation given

⇒ 3(x^{2} -4x+9)=0

dividing both side by 3

⇒ x^{2} -4x+9=0

By using different factor, we can observe this trinomial can not be factored.

∴ solving it by completing the square.

⇒ x^{2} -4x+9=0

adding 9 on both side

⇒ x^{2} -4x= 9

To get a perfect square number as coeffecient of x is 4, lets add both side by 4.

⇒x^{2} -4x+4= 13

we know, (x+2)^{2} = x^{2} +2\times x\times 2+2^{2}

∴ (x+2)^{2} =13

Taking Square root on both side, remember; √a²= a

⇒ (x+2)= \sqrt{13}

opening parenthesis

⇒ x+2= \sqrt{13}

subtracting both side by 2

∴ x= -2 \pm \sqrt{13}
